    Abstract

    Most of previous photocatalysts contain metal species, thus exploring a metal-free photocatalyst is still challenging. A metal-free photocatalyst has an advantage for the development of economical and non-toxic artificial photosynthesis system and/or environmental purification applications. In this study, rhombohedral boron monosulfide (r-BS) was synthesized by a high-pressure solid-state reaction, and its photocatalytic properties were investigated. r-BS absorbed visible light, and its photocurrent action spectrum also exhibited visible light responsivity. The r-BS evolved hydrogen (H2) from water under ultraviolet (UV) as well as under visible light irradiation, and its internal quantum efficiency reached 1.8% under UV light irradiation. In addition to the H2 evolution reaction, the r-BS photocatalyst drove carbon dioxide (CO2) reduction and dye oxidation reactions under UV irradiation. Although bare r-BS was not so stable under strong light irradiation in water, cocatalyst modification improved its stability. These results indicate that r-BS is a new class of non-metal photocatalyst applicable for H2 production, CO2 reduction, and environmental purification reactions.

    Hydrogen boride (HB) sheets are two-dimensional materials comprising a negatively charged hexagonal boron network and positively charged hydrogen atoms with a stoichiometric ratio of 1:1. Herein, we report the spontaneous formation of highly dispersed Ni nanoclusters on HB sheets. The spontaneous reduction reaction of Ni ions by the HB sheets was monitored by in-situ measurements with an ultraviolet-visible spectrometer. Acetonitrile solutions of Ni complexes and acetonitrile dispersions of the HB sheets were mixed in several molar ratios (the HB:Ni molar ratio was varied from 100:0.5 to 100:20), and the changes in the absorbance were measured over time. In all cases, the results suggest that Ni metal clusters grow on the HB sheets, considering the increase in absorbance with time. The absorbance peak position shifts to the higher wavelength as the Ni ion concentration increases. Transmission electron microscopy images of the post-reaction products indicate the formation of Ni nanoclusters, with sizes of a few nanometers, on the HB sheets, regardless of the preparation conditions. These highly dispersed Ni nanoclusters supported on HB sheets will be used for catalytic and plasmonic applications and as hydrogen storage materials.

    Photocatalysts are promising materials for solid-state antiviral coatings to protect against the spread of pandemic coronavirus disease (COVID-19). This paper reports that copper oxide nanoclusters grafted with titanium dioxide (CuxO/TiO2) inactivated the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, including its Delta variant, even under dark condition, and further inactivated it under illumination with a white fluorescent bulb. To investigate its inactivation mechanism, the denaturation of spike proteins of SARS-CoV-2 was examined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and enzyme-linked immunosorbent assay (ELISA). In addition to spike proteins, fragmentation of ribonucleic acids in SARS-CoV-2 was investigated by real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR). As a result, both spike proteins and RNAs in the SARS-CoV-2 virus were damaged by the CuxO/TiO2 photocatalyst even under dark condition and were further damaged under white fluorescent bulb illumination. Based on the present antiviral mechanism, the CuxO/TiO2 photocatalyst will be effective in inactivating other potential mutant strains of SARS-CoV-2. The CuxO/TiO2 photocatalyst can thus be used to reduce the infectious risk of COVID-19 in an indoor environment, where light illumination is turned on during the day and off during the night.

    <title>Abstract</title>Boron-based two-dimensional materials are of interest for use in electronic devices and catalytic applications, for which it is important that they are chemically stable. Here, we explore the chemical stability of hydrogen boride nanosheets in water. Experiments reveal that mixing hydrogen boride and water produces negligible amounts of hydrogen, suggesting that hydrolysis does not occur and that hydrogen boride is stable in water, which is in contrast to most boron hydride materials. First-principles calculations reveal that the sheets interact weakly with water even in the presence of defects and that negatively charged boron prevents the onset of hydrolysis. We conclude that the charge state of boron and the covalent boron-boron bond network are responsible for the chemical and structural stability. On the other hand, we found that proton exchange with hydrogen boride nanosheets does occur in water, indicating that they become acidic in the presence of water.

    Photocatalysis is an effective technology for preventing the spread of pandemic-scale viruses. This review paper presents an overview of the recent progress in the development of an efficient visible light-sensitive photocatalyst, i.e., a copper oxide nanoclusters grafted titanium dioxide (CuxO/TiO2). The antiviral CuxO/TiO2 photocatalyst is functionalised by a different mechanism in addition to the photocatalytic oxidation process. The CuxO nanocluster consists of the valence states of Cu(I) and Cu(II); herein, the Cu(I) species denaturalizes the protein of the virus, thereby resulting in significant antiviral properties even under dark conditions. Moreover, the Cu(II) species in the CuxO nanocluster serves as an electron acceptor through photo-induced interfacial charge transfer, which leads to the formation of an anti-virus Cu(I) species and holes with strong oxidation power in the valence band of TiO2 under visible-light irradiation. The antiviral function of the CuxO/TiO2 photocatalyst is maintained under indoor conditions, where light illumination is enabled during the day but not during the night; this is because the remaining active Cu(I) species works under dark conditions. The CuxO/TiO2 photocatalyst can thus be used to reduce the risk of virus infection by acting as an antiviral coating material.

    Two-dimensional (2D) materials are promising for applications in a wide range of fields because of their unique properties. Hydrogen boride sheets, a new 2D material recently predicted from theory, exhibit intriguing electronic and mechanical properties as well as hydrogen storage capacity. Here, we report the experimental realization of 2D hydrogen boride sheets with an empirical formula of H1B1, produced by exfoliation and complete ion-exchange between protons and magnesium cations in magnesium diboride (MgB2) with an average yield of 42.3% at room temperature. The sheets feature an sp(2)-bonded boron planar structure without any long-range order. A hexagonal boron network with bridge hydrogens is suggested as the possible local structure, where the absence of long-range order was ascribed to the presence of three different anisotropic domains originating from the 2-fold symmetry of the hydrogen positions against the 6-fold symmetry of the boron networks, based on X-ray diffraction, X-ray atomic pair distribution functions, electron diffraction, transmission electron microscopy, photo absorption, core-level binding energy data, infrared absorption, electron energy loss spectrosco

    Superplasticizer(S.P.)is used in almost all concrete, made in Japan, to decrease the amount of water. Now the use of hot-weather concrete is increasing. And interstitial phase of cement such as C3A, C4AF will be increased for keeping usage amount of by-products. In these cases, early hydration will make great influence on fluidity of cement paste. Therefore, the role of chemical admixture, especially S.P. is getting more important. It is pointed out that the fluidity change of concrete with the lapse of time is influenced by the molecular structure of S.P.. However the mechanism of fluidity change is not clear. And it is necessary to advance the research on the interaction between cement and S.P.. We focused on the action mechanism of S.P. especially in the early stage of hydration. In this study, it was pointed out that polycarboxylate based S.P. has better fluidity retaining performance than Naphthalene sulfonate based S.P.. It was thought that this difference was related to the difference of the amount of adsorbed S.P. per specific surface area. It has been shown that the fluidity deterioration of cement paste with Naphthalene sulfonate based S.P. is attributed by the decrease of residual concentration of S.P. in liquid phase.

    Two-dimensional (2D) materials consisting of a single or a few layers of atoms have superior performance as compared to conventional materials or their bulk counterparts. Combining 2D materials through layer stacking in a controlled manner can also produce several novel functionalities in the form of new three-dimensional (3D) layered materials (van der Waals heterostructures) [1]. Therefore, synthesis of new 2D materials opens several pathways for the applied use of van der Waals heterostructures. The purpose of this study was to synthesize r-BS at high temperature and high pressure, and to synthesize and evaluate nanosheets by exfoliation. X-ray photoelectron spectroscopy, Raman scattering, transmission electron microscope (TEM), electron energy loss spectroscopy (EELS), energy dispersive X-ray spectroscopy, atomic force microscope, cathodoluminescence, etc. for the synthesized r-BS and exfoliated sample It was evaluated by measurement.

    We have revealed that the hydrogen boride (HB) sheet can be synthesized by ion-exchange in magnesium diboride (MgB2). HB sheets release their hydrogen as H2 molecules by heating in a wide temperature range. Theoretical calculations have reported that the bond between H and B weakens due to electron doping, so the hydrogen desorption temperature can be expected to be lowered by the electron doping. In this work, we synthesized and evaluated carbon doped (C-doped) HB sheets by using C-doped MgB2 as a starting material.

    Recently, we have revealed that the hydrogen boride (HB) sheets can be formed by exfoliation and complete ion-exchange between protons and magnesium cations in magnesium diboride (MgB2+2H → Mg2++2HB) at room temperature and ambient pressure. We have then found that the hydrogen molecules (H2) can be released from HB by the UV irradiation as much as 8 wt% at room temperature.

    Yttrium oxyhydride (YOxHy) exhibits unique photochromic properties in electrical resistivity and optical transparency, attracting photoelectronic applications such as smart windows and optical sensors. To enhance the photo-induced physical-property variation, in this study, we attempted 1): epitaxial growth of YOxHy thin films, and 2): irradiation of ultraviolet laser. Consequently, we achieved reversible change in resistivity by 7 orders of magnitude, in clear contrast to that previously reported in polycrystalline thin films using sunlight (one order of magnitude). Furthermore, we found that temperature dependence of resistivity was metallic after the irradiation of UV laser to the YOxHy thin film.

    High-strength high-durability cement is used these days, and it consists of low heat Portland cement(LHC)and silica fume(SF). However, LHC-SF system is uneconomical and utilizes a small amount of industrial wastes. In contrast, moderate-heat Portland cement(MPC)utilizes more industrial wastes, and the limestone powder(LSP)is an economical material. Therefore, MPC-LSP system is expected as the new high-durability cement. This paper investigates the fluidity of low water-to-powder ratio MPC-LSP paste with superplasticizer from the point of the packing fraction and the initial hydration. To make the fluidity higher, the authors used the packing simulation, and the LSP mass ratio to MPC was configured to make the highest packing fraction. The fluidity of configured MPC-LSP paste was higher than that of LHC-SF paste. In addition, the increase in the LSP ratio to MPC increased the fluidity of MPC-LSP paste, and this tendency was stronger at low water-to-powder ratio. On the other hand, the cumulative heat liberation of MPC-LSP paste was lower than that of LHC-SF paste. In addition, the increase in the LSP ratio to MPC decreased the cumulative heat liberation of MPC-LSP paste, and this tendency corresponded with the fluidity. It is considered that LSP influenced on the initial hydration of calcium-aluminate phase in cement, resulting in the higher fluidity. The initial hydration is an important factor in the fluidity of cement paste.

    Industrial waste with silica components is anticipated as an alternative resource for silica stone, which is the main material for Autoclaved Lightweight Concrete (ALC) Panels. Using cements and silica stone powder as main raw materials, ALC panels can be produced to have heat resistance and long-term stability because of their tobermorite crystalline contents. Tobermorite generation requires hydrothermal synthesis under saturated steam pressure at 180 °C. This study assessed glass waste availability as an alternative resource for silica stone. Candidates were tiles and pot shard waste, liquid crystal glass, and glass bottles. Considering the influence on hydration products, these were evaluated using X-ray powder diffraction (XRD) analysis. Results show that the optimum replacement of silica stone powder with tiles and pot shards waste was approximately 25 % to produce tobermorite formation and dense structure. Calculating the demand of alternative resources and the supply of tiles and pot shard waste, results suggest that the 80 % of its annual emissions are useful.

    Retarders(ex. Sucrose)are used to control the hydration of cement in concrete. The effect of retarder may change in low-temperature calcined cement containing fluoride, but there is no research about this point. In this study, authors investigated the influence of fluoride addition on the hydration, the specific surface area of the solid phase, and the amount of adsorbed retarder in cement paste containing retarder. Sucrose, sodium gluconate, dextrin, and K3PO4 were used as the retarder. The hydration of cement with sucrose was less retarded in cement paste with KF, i.e. the effect of sucrose was weakened by KF addition. In contrast, the hydration of cement with sodium gluconate, dextrin, or K3PO4 was more retarded in cement paste with KF, i.e. the effect was enhanced by KF addition. Since the specific surface area and the amounts of adsorbed organic retarders increased with KF addition, it is supposed that some types of fine particles were generated by KF addition and retarders adsorbed to the particles. It is supposed that the sucrose’s preferential adsorption to the particles decreased the amount of adsorbed sucrose on cement particles and caused the decrease in the effect of sucrose on the hydration. In contrast, the increase in the effect of sodium gluconate, dextrin, and K3PO4 cannot be explained by the preferential adsorption. It is supposed that the increase in the effect relates to the synergy between the effect of these three retarders and the effect of fluoride precipitation on cement particles.

    The influence of the curing temperature on the compressive strength and the maximum expansion of the cementitious material based on the OPC-AC-CS system were examined. The influence of the curing temperature was differed from OPC/AC ratio. In the case of OPC/AC ratio 3.00, the compressive strength decreased with decreasing curing temperature. On the other hand, the compressive strength was highest at 5℃ in the case of OPC/AC ratio 0.33 and 1.00. If curing temperature was same, the compressive strength was related with the porosity in spite of OPC/AC ratio. However, the dependence of the compressive strength to the porosity was differed from the curing temperature. From the analysis of the phase composition which calculated from the reaction ratio of main mineral, the reason of the tendency was guessed that the difference of the kind and amount of hydrate. On the other hand, the maximum expansion was increased with increasing OPC/AC ratio and decreasing curing temperature. From SEM observation, small ettringite was formed in the expanded samples. In addition, there were tendency that the amount of C-S-H gel which calculated from the reaction ratio of C3S was a lot compare with non-expanded condition. Therefore, it was guessed that the maximum expansion was increased because ettringite was formed in the dense matrix.

    Titanium dioxide(TiO2)photocatalyst has been widely coated on various substrates for environmental issues. Among various substrates, cement based material is one of the largest mass-products, and that with photocatalytic function causes great attraction to the market demand. Cement based materials are usually treated under a hydrothermal condition in industrial manufacturing process, since it is hardened by hydrate reaction. In the present study, we have focused on the hydrothermal treatment for the crystallization of TiO2 coating as well as the hardening of bulk. But the development of TiO2 coating on cement based materials by hydrothermal treatment is challenging issue, since the surface of cement based materials contains free ions like Ca2+, which limit the crystallization of TiO2 film onto the substrate. Calcium ions easily react with amorphous TiO2 under hydrothermal condition to form photocatalytically inactive CaTiO3. Herein, we have two ideas for developing the photocatalytically active crystalline TiO2 onto cement based materials, i. e. surface carbonation as pretreatment and addition of α-Quartz into bulk. Surface carbonation forms calcium carbonate to reduce the free Ca2+ ions, while the addition of α-Quartz also react with the calcium ions species in bulk. We used the titanium tetra-isopropoxide as initial coating solution and investigated the effects of surface carbonation, α-Quartz addition, and hydrothermal conditions on the crystallization of TiO2 and its photocatalytic activity. On the basis of these ideas, we have succeeded to develop the photocatalytically active TiO2 coating onto cement based materials and established the strategic method of TiO2 coating onto an unstable substrate like cement.

    This paper investigated the influence of sodium gluconate on the hydration of cement in sludge water. And the interaction between sodium gluconate and calcium aluminate was also investigated.<br/>The rate of heat liberation of ordinary Portland cement paste with sodium gluconate was measured by using conduction calorimeter. The concentration of residual sodium gluconate in liquid phase was calculated by carbon analysis using a total organic carbon analyzer(TOC). And the adsorbed amount of sodium gluconate was calculated from the concentration of residual sodium gluconate.<br/>The hydration rate of alite was retarded by addition of sodium gluconate. And the hydration of calcium aluminate in cement was also retarded by adding of sodium gluconate. The adsorption behavior of sodium gluconate onto calcium aluminate did not obey the Langmuir adsorption. There was the linear relation between dosage and adsorbed amount of sodium gluconate. And the interaction between calcium aluminate and sodium gluconate was very strong. So it is considered that late-addition of sodium gluconate for cement sludge is effective to control the hydration of alite in cement sludge. And the hydration of cement with comb-type superplasticizer was retarded by addition of sodium gluconate. So we can consider that sodium gluconate is also effective to control the hydration of alite with superplasticizer in sludge water.

Sulfate and fluoride is prospective ingredient to lower calcinations temperature \nof cement manufacturing for environmental reduction. This paper discusses the influence of sulfate ion and fluoride ion on the fluidity of cement paste and the adsorption of polycarboxylate based superplastisizer having different molecular structure. Using a control stress type rheometer(rotational cylinder viscometer), the viscosity of the suspension was measured to estimate the apparent viscosity at a shear stress of 200 Pa. The adsorbed amount of superplasticizer calculated from the concentrations of the superplasticizer in the initial solution and the liquid phase. The unadsorbed superplasticizer concentration was measured by carbon analysis using a total organic carbon analyzer(TOC). Three types polycarboxylate based superplasticizer P-70, P-34 and P-10 were used in this study. The number expresses the degree of polymerization of grafted chain. When the concentration of inorganic ion rose, the apparent viscosity and the amount of adsorbed superplasticizer increased. In the case of K2SO4 addition, the apparent viscosity of cement paste with P-10 was smaller than that with P-34. On the contrary, in the case of KF addition, P-34 indicated the smaller apparent viscosity than P-10. The amount of adsorbed P-10 was larger than that of P-34.

    Low-temperature calcination for cement manufacturing by the addition of fluoride compounds has been researched by many investigators. Although it is possible that fluoride ions elute to the suspension after calcination, there are very few studies about the influence of fluoride ion on the fluidity of cement paste with superplasticizer. This paper describes the influence of the fluoride ion on the adsorption mechanism of polycarboxylate based superplasticizer and naphthalenesulfonate based superplasticizer in cement paste. When the amount of added KF was increased, the viscosity of the cement paste with superplasticizer and the amount of adsorbed superplasticizer increased. The specific surface area increased with KF addition. In the case of no KF addition, the hydration of alite was retarded by the addition of polycarboxylate based superplasticizer. In contrast, in the case of KF addition, the hydration of alite was not retarded by the addition of superplasticizer. We suggest that fine CaF2 particles were generated by KF addition and CaF2 deprived the cement particles of superplasticizer.

    The Portland Cement (OPC)Calcium Aluminate Cement (AC)-anhydrite(CS) system is useful for various construction materials because it Can provide various physical properties by adjusting the mix proportions. For example, this system is used for cementitious material to provide the properties of early drying, rapid hardening, and small length change. However, this system is very sensitive to mix-proportion, temperature and the quality of raw materials, which is a significant problem. On the other hand, it’s important to use much by-product such as Blast furnace slag(BFS) for the environmental. So, we examined about the hydration and compressive strength of the cementitious material based on the OPC-AC-CS system as basic study for the foundation of the OPC-AC-CS-BFS system. The compressive strength of this cementitious material was especially depended on the OPC/AC ratio. From the hydration analysis of the OPC-AC-CS system, we found that their phase compositions that calculated from the reaction ratio of the main minerals were completely different. In the case of the OPC/AC ratio 3.00, ettringite and C-S-H gel were main hydrate. On the other hand, in the case of the OPC/AC ratio 0.33 and 1.00, ettringite and C-A-H gel were main hydrate. However, the compressive strength correlated with the gel pore ratio in spite of the OPC/AC ratio. Therefore, in the range of our study, we guessed the reason of the difference of the compressive strength was the difference of the gel pore ratio. However, on the other hand, the amount of C-A-H gel related to compressive strength, so we have to examine about the deference of the elastic behavior of the hydrate in future study.

    We designed and fabricated novel TiO2-based visible-light-sensitive photocatalysts, in which Fe(III)or Cu(II)species were grafted on a TiO2 surface. These showed high photocatalytic activity under indoor light conditions, demonstrating air-cleaning, antiviral, and self-cleaning effects. Recently, we evaluated the antibacterial and antiviral activities of these materials in an airport terminal and hospital, where the risks of infection are high, and confirmed that the novel visible-light-sensitive photocatalysts are effective against bacteria in actual indoor environments.

    Reducing emission of CO2 is the most important problem in the cement industry. And cement industry must contribute to recycling by utilization of industrial waste and by-products as raw materials or fuel. Recently, blast furnace cement has been noted for environmental loading reduction. This paper discusses the adsorption and the dispersion mechanism of comb-type superplastisizer having different molecular structure as the blended blast furnace cement.Using a control stress type rheometer(rotational cylinder viscometer), the viscosity of the suspension was measured to estimate the apparent viscosity at a shear stress of 200 Pa. The absorbed amount of polymer calculated from the concentrations of the polymer in the initial solution and the liquid phase. The unabsorbed polymer concentration was measured by carbon analysis using a total organic carbon analyzer(TOC).Comb-type superplasticizer having smaller amount of functional groups is adsorbed on BFS compared with OPC. And comb-type superplasticizer having larger amount of functional groups is adsorbed on both BFS and OPC. In the case of comb-type superplasticizer having larger amount of functional groups, the fluidity of cement paste was influenced by the replacement ratio of BFS. On the other hand, in the case of comb-type superplasticizer having smaller amount of functional groups, the fluidity of cement paste was not influenced by the replacement ratio of BFS. Therefore comb-type superplasticizer having smaller amount of functional groups could be suitable for blended cement.

    Thermoporometry is watched as new analytical approach for characterizing pore structure as a measuring method of substitution of Mercury Intrusion Porosimetry. Hardened cement has wide range of pore size distribution around 2nm to 200nm, and it is necessary to analyze melting or freezing behavior of water about -0.1℃ when measuring the large pore around 200nm. But it is difficult to measure correctly by differential scanning calorimeter. On the other hand, reduction of melting point of cyclohexane is larger than that of water, and it is suitable to measure large pore. This study discussed melting behavior of freeze water and cyclohexane in porous silica, and suggested the method which combined with melting behaviors of freeze water and cyclohexane to measure pore size distribution of hardened cement as compared with Mercury Intrusion Porosimetry. It found that water is suitable for measurement of the pore below 15nm, and cyclohexane is suitable more than it. Pore structure of hardened cement is able to be analyzed by new method. In addition, this method has possibility that measure the pore structure of deteriorated hardened cement by sulfuric acid. However, Mercury Intrusion Porosimetry could not measure the pore structure, and deteriorated sample collapsed when the pressure is. about 0.1MPa.

    Most ready-mixed concrete plants have a problem of construction waste sludge, which causes environmental pollution and economic loss. A cement sludge recycling system is therefore highly desirable.<br/>Japanese Industrial Standard(JIS)A 5308 permits the addition of 3% sludge(as solid state)to cement in concrete. However, it is pointed out that a reduction of fluidity and increase in water demand occur upon utilization of sludge. To achieve more widespread recycling of sludge by using set-retarders, we have to establish the evaluation method of residual cement content of sludge.The rate of heat liberation of ordinary Portland cement paste was measured by using conduction calorimeter. And the residual amount of sodium gluconate was measured by Total Organic Carbon Analyzer(TOC).<br/>The residual alite amount of cement paste by XRD quantity method was related to the heat liberation of cement paste. It is concluded that the residual alite amount of cement paste can be estimated by conductive type calorimeter. The amount of residual alite of cement paste can be evaluated swiftly by using conductive type calorimeter and Mg(NO32・6H2O. When the Mg(NO32・6H2O was added, the retardation of cement hydration with sodium gluconate was decreased. It is considered that the acceleration mechanism of Mg(NO32・6H2O is the decreasing of sodium gluconate concentration in liquid phase.

Visible light activities of the developed photocatalyst are much better than those of previously reported materials like nitrogen doped TiO_2. Developed photocatalysts exhibit various functions, such as air purification, self-cleaning, and anti-pathogenic properties even under indoor light illumination. Synthetic method for our Cu(II) or Fe(III) amorphous nanoclusters grafted TiO_2 is very simple and can be adapted for mass production at a low cost. We expect that our photocatalysts can be applied to various indoor scenes, such as private housings, office buildings, hospitals, airports, metro stations, schools, and so on.

    Nitrogen doped TiO_2 films were prepared by annealing TiO_2 films in NH_3 atmosphere. XPS results revealed that nitrogen was doped into substitutional sites of anatase type TiO_2 lattice. Zeta potentials of these films were evaluated, and as a result, nitrogen doping induced the surface zeta potential to more negative. Further, we also evaluated photocatalytic properties of these films.

    We have prepared nitrogen doped TiO2 films by annealing TiO2 films in NH3 atmosphere, and have evaluated XPS, XRD, SEM, and zeta potential for these films. XPS results revealed that nitrogen was doped into substitutional sites of anatase type TiO2 lattice. As for the zeta potential, nitrogen doping induced the surface zeta potential to more negative. Isoelectric point of N-doped TiO2 (in terms of pH) was about 1.0, whereas that of TiO2 was 6.0. Further, in the present study, we also evaluated photocatalytic activities of these films.

    Photoinduced hydrophilicity of heterogeneous TiO_2/WO_3 films was evaluated. The addition of WO_3 on TiO_2 enhanced the photo-induced hydrophilicizing rate, however, it decreased the photocatalytic oxidation property. The heterogeneous TiO_2/WO_3 film became highly hydrophilic even under the fluorescent light with very weak intensity (UV intensity : 1μW/cm2).

    Photo-induced hydrophilic properties of various photocatalysts have been evaluated. Among various photocatalysts, TiO_2,SnO_2,ZnO, WO_3 and V_2O_5 become hydrophilic under UV irradiation. In particular, the WO_3 surface becomes hydrophilic even under visible light irradiation. In order to enhance the photo-induced hydrophilic property, we have fabricated the heterogeneous TiO_2/WO_3 thin film and evaluated its hydrophilicity under a fluorescent light of weak intensity (10μW/(cm)^2). The TiO_2/WO_3 film exhibits higher hydrophilicizing rate than the homogeneous TiO_2 film.

    Morphology of PZT films varied with the amount of raw materials and [OH^-]. Precipitation as films and as powders increased with increasing the amount of raw materials. The more porous film derived, the more starting materials existed. When [OH^-] increased, yield of the film decreased, however that of PZT powders increased. This indicated that the nucleation in the solution was predominant than the nucleation on the substrate at higher [OH^-] condition.

    Crystalline PZT films can be formed by hydrothermal method, however, chemical composition was inhomogeneous when the film was synthesized in a testtube type autoclave. Because the concentration of cach ion(Pb, Zr and Ti) in solution was not able to control. A continuous supplying autoclave system was fabricated to form PZT films with controlling their chemical compositions, under hydrothermal conditions. Solutions were sampled from the reactor during reaction time, and the change in concentration of solution was decided from that results, and the chemical composition of synthesized film was...

    Interfacial charge transfer (IFCT) is known to drive photocatalysis under visible light. However, its mechanism study is insufficient and its reactions are limited to the organic decomposition. Herein, the purpose of this study is to prove the IFCT mechanism clearer and to achieve the photocatalytic overall water splitting under visible light using the IFCT mechanism. Based on a well-defined thin film model sample, I successfully visualized the IFCT by Kelvin probe force microscopy. In addition, chemical reaction sites are also visualized by observing photo-deposited metal particles by atomic force microscopy. Further, we fabricated the Cu(II) nanoclusters-grafted TiO2 electrode and achieved its water splitting reaction under visible light.

    α- and β- phase MnO2 were synthesized and their electrochemical water oxidation activities were examined. As a result, both of them demonstrated an increase of water oxidation activity by the addition of pyridine. In contrast, in in situ spectroscopic measurements, the absorbance of Mn3+, which act as the active species, disappeared by the addition of pyridine in the case of β-MnO2. This phenomenon cannot be explained by conventional reaction mechanism. Additional electrochemical and spectroscopic analysis revealed that pyridine coordinated to MnO6 octahedra, resulting in the acceleration of interface charge transfer.

    We have developed the highly efficient visible-light-sensitive photocatalyst on the basis of CuOx and Ti(IV) oxides nanoclusters grafted TiO2 by a facile wet chemical synthesis. Charge transfer process in this photocatalyst has been elucidated by spectroscopic analysis and probe microscope onto the thin film model structure. Based on these results, the choice of metal oxides with appropriate work function and its size of a few nanometers are very important for the development of efficient photocatalyst. Our photocatalyst is working as an anti-bacterial and deodorization building material even under indoor environment, which has been commercialized.

    本研究ではデバイス構造として、透明導電膜の上に多孔質TiO2層があり、TiO2表面に硫化物量子ドットが担持され、更に量子ドットの表面にホール輸送相となるPEDOTをコートした電極を考案し、高耐久で優れた光電変換素子と水分解光触媒を開発した。
    量子ドットの合成は、Successive Ionic Layred Absorption and Reaction (SILAR)法を用い、CdSないしCdSe量子ドットを多孔質酸化チタンの表面に担持した。SILAR法の回数によって量子ドットのサイズを制御することができ、それらの光学的バンドギャップが粒子サイズに依存する量子効果が確認できた。最も高い光電流特性を示した量子ドットのバンドギャップは、CdSが2.4 eV, CdSeが1.7 eVを示し、バルクのバンドギャップよりも若干大きな値を示した。また、量子ドットのコートの順序はTiO2上にCdSを担持し、さらにその上にCdSeをコートしたサンプルが高い光電変換特性を示した。CdSよりもCdSeの方が伝導帯の電位が高いため、TiO2/CdS/CdSeの順に積むことでTiO2への電子注入がスムーズに進行したものと考えられる。一方、PEDOTは電気化学パルス法によって成膜したが、パルス回数によってPEDOTの厚さを制御することができた。光電流に対する最適なPEDOTの厚さが存在し、パルス回数が6回、すなわち、PEDOTの厚さが5nm程度のサンプルが高い光電変換特性を示した。これらの電極を犠牲剤が含まれる電解液内で、かつ、無バイアス条件下で可視光を照射し、水素生成特性を評価した。この結果、優れた水分解特性が得られ、水素生成速度は光照射の単位面積あたり370 (umol/cm2/hour)、量子効率は6.9 %と量子ドット系では世界最高レベルに近い値を示した。また、PEDOTのコートによって耐久性が劇的に改善され、触媒量に対する水素生成量、すなわち、ターンオーバー数も2210を超え、優れた長期的安定性が確認できた。

    平成23年度は前年度に得られた高活性光触媒粉末材料の更なる高活性化を検討した。前年度の成果である酸化亜鉛光触媒に加え、酸化タングステンでも高度な可視光活性を発現する材料の開発に成功した。特に、酸化タングステンの表面に酸化チタンナノ粒子とアモルファス状酸化銅クラスターを担持することで高度な可視光活性が発現した。本研究で得られた光触媒は既往の研究で報告されている窒素ドープ型酸化チタンよりも高い可視光活性(量子効率)を示した。活性向上の機構として、様々な解析により酸化タングステンから酸化チタンへの正孔の移動に起因していることを明らかにした。また、平成23年度は、これらの高活性光触媒材料をベースに薄膜コーティングを検討した。特に、ガラス基材の上に白金助触媒、その上に酸化タングステン、更にその上に酸化チタン薄膜をコーティングした積層薄膜を開発し、白色蛍光灯の様な室内照明で自己浄化(セルフクリーニング機能)を発揮する画期的な部材を開発することができた。高度なセルフクリーニング機能を発現させるための因子として、積層薄膜の空孔率や酸素透過性が重要であることを見出した。この薄膜の全厚さは約100nm程度で、目視での透明性も高い。また、ゾルゲル法で成膜できるので、低コスト・大面積化が期待できる。開発した薄膜は高度なセルフクリーニング機能に加え、表面に酸化チタンをコーティングすることで、化学薬品への耐久性にも優れるといった副次的機能も発現した。セルフクリーニング機能以外にもVOC(揮発性有害化合物)の分解といった空気浄化機能も確認でき、光触媒の室内用途拡大が期待できる画期的な部材を開発することができた。
