    <jats:title>Abstract</jats:title><jats:p>The hydrogenation of CO<jats:sub>2</jats:sub> to methanol has garnered significant interest with respect to the reduction of carbon emissions; however, the high temperatures and pressures typically required diminish the benefits of this approach. In this study, we report a hexagonal close‐packed (hcp)‐PdMo catalyst that exhibits the highest room temperature catalytic activity for CO<jats:sub>2</jats:sub> hydrogenation to methanol among reported catalysts, with 100% methanol selectivity and without any signs of deactivation. Structural analyses, which included various in situ and ex situ X‐ray techniques and infrared spectroscopy, have revealed that Mo and Pd serve as the active sites for CO<jats:sub>2</jats:sub> adsorption and H<jats:sub>2</jats:sub> dissociation, respectively. The CO<jats:sub>2</jats:sub> hydrogenation reaction is facilitated at room temperature on the surface of the hcp‐PdMo intermetallic catalyst, where the adjacently arranged Pd and Mo sites play important roles in methanol synthesis. Mechanistic studies, combined with density functional theory (DFT) calculations, have demonstrated that the reaction proceeds via a reverse water‐gas shift and subsequent CO hydrogenation (R&amp;C) pathway though a Pd‐assisted Mo redox mechanism at room temperature. These findings not only reveal the origin of the reaction mechanism for methanol synthesis but also open a new direction for the design of highly efficient catalysts that function under mild conditions.</jats:p>

    Abstract

    Oxyhydrides have attracted attention as materials with various unique properties derived from lattice hydride ions (H). However, their instability makes synthesis by conventional thermal synthesis methods difficult, so an appropriate synthesis strategy is required. Here, the mechanochemical synthesis of perovskite oxyhydrides BaREO2H (RE = Y, Sc) for catalyst applications is reported. The formation of BaYO2H is known to be thermodynamically unstable; however, a mechanochemical process that inevitably proceeds under non‐equilibrium conditions enables the synthesis of such a metastable oxyhydride material without any heat treatment. Furthermore, BaScO2H, which is typically obtained at very high temperatures (1000 °C) and pressure (&gt;4 GPa), is successfully synthesized at room temperature by the mechanochemical method. The ammonia synthesis reaction over these oxyhydrides supporting Ru is significantly enhanced at low temperatures, and the ammonia synthesis rates are significantly higher than conventional oxide‐supported Ru catalysts. The mechanochemically synthesized BaREO2H has many anionic electrons with low work function at the site of H vacancies, which enables strong electron donation to Ru and the storage of excess hydrogen adatoms from the Ru surface that results in high catalytic performance.

    Abstract

    Barium oxide is a conventional promoter for various transition‐metal (TM) catalysts in ammonia synthesis. Ba‐promoted Ru catalysts are widely used for ammonia synthesis under mild reaction conditions. However, the promotion mechanism, including the active factor, remains unclear. In this study, the excellent promotion effect of barium oxynitride is reported, which creates anionic electrons in the lattice, forming an electride (BaOxNy:ez) with the same rocksalt structure as BaO. The BaOxNy:ez enhances the ammonia synthesis activity of the supported Ru catalyst by 40–100 fold compared with the BaO promotor. This study reveals that a low‐work‐function electron formed in the BaO lattice plays a pivotal role in the electronic promotion effect in catalytic ammonia synthesis, suggesting that BaOxNy:ez formed near the surface during the ammonia synthesis reaction is an active species for the promotion effect of conventional BaO.

    Topological materials have received much attention because of their robust topological surface states, which can be potentially applied in electronics and catalysis. Here, we show that the topological insulator bismuth selenide functions as an efficient catalyst for the oxidative carbonylation of amines with carbon monoxide and dioxygen to synthesize urea derivatives. For example, the carbonylation of butylamine can be completed over bismuth selenide nanoparticle catalyst in 4 hours at 20°C with a yield of 99%, whereas most noble metal–based catalysts do not function at such a low temperature. Density functional theory calculations further reveal that the topological surface states facilitate the activation of dioxygen through a triplet-to-singlet spin-conversion reaction, in which active oxygen species are formed with a barrier of 0.4 electron volts for the subsequent reactions with amine and carbon monoxide.

    Highly dispersed active metal supported on hydride materials can be synthesized by light irratiation of hydride. Hexagonal-BaTiO(3-x)Hx can be synthesized by direct reaction of BaH2 and TiO2 under hydrogen flow. The Pd nanoparticles prepared by activation of hydride in this material by light irratiation was found to be more highly dispersed than those prepared by the conventional impregnation method. The prepared Pd-supported BaTiO(3-x)Hx catalyst showed higher activity and styrene selectivity for phenylacetylene hydrogenation thatn the conventional oxide-supported catalysts.

    Pd系金属間化合物に対してガルバニック置換法を適用することにより、他種金属による表面修飾を行った。調製した触媒を用いた触媒的水素移動反応(CTH)について検討したところ、シリカ担持Pd5Ga3金属間化合物に対して表面修飾した触媒は元の金属間化合物とは異なる触媒特性を示した。特にFeによって修飾したPd5Ga3はメチルシクロヘキサンを水素源として用いたニトロスチレンの水素化において、高いビニル基選択性および活性を示し、置換前の金属間化合物よりもエチルニトロベンゼン収率が向上した。また、触媒調製法の影響を検討するため、この触媒と同等の組成を持つ合金触媒を共含浸法によって調製し、触媒特性の比較を行った。その結果、ガルバニック置換法によって調製した触媒は合金よりも顕著に高い触媒活性を示し、Fe修飾Pd5Ga3の触媒特性は表面構造に起因することが明らかになった。
    また、調製した触媒は置換前後で粒子の形状および内部構造が維持されており、さらに、触媒表面上に吸着したCOのIR測定を行ったところ、Feを用いて表面修飾することによって、Pdの表面配列が異なることが明らかになった。すなわち、Feの表面修飾によって表面のPdブリッジサイト数が増加し、リニアサイト数が減少した。また、置換前と比較してPdの電子密度が増加することが明らかになった。よって、これらの表面構造および電子状態の変化によってFe置換によってPd5Ga3の触媒特性が向上したと考えられる。
