    Hydrogen boride (HB) nanosheets, which exhibit unique BHB bonding and intrinsic hydrogen release properties, show improved performance upon carbon doping. Herein, the synthesis of carbon‐doped HB via ion exchange is demonstrated by using carbon‐doped MgB 2 as a precursor. Comprehensive spectroscopic analyses inferred carbon substitution at boron sites, leading to structural distortions and electronic modifications. These changes weaken BHB bonds, thereby facilitating improved hydrogen release under both thermal and ultraviolet (UV) stimuli. Temperature‐programed desorption measurements reveal a reduction in the activation energy for intralayer hydrogen desorption with increasing carbon content, while UV‐induced hydrogen evolution shows a markedly lower onset threshold. Density functional theory calculations support these experimental findings, further demonstrating elongation of BB distances and shifts in vibrational modes. Overall, these results establish carbon doping as an effective strategy for modulating the chemical and electronic environment of HB, offering a promising pathway toward high‐efficiency, tunable hydrogen storage, and release materials.

  • Sulfur Doping to Cu 3 N Electrocatalyst Enhanced CO 2 Reduction to CH 4 Reviewed International journal

    Although metal sulfides are promising catalysts for the electrochemical carbon dioxide (CO 2 ) reduction reaction, repulsion between the lone pair of oxygen electrons of CO 2 and the electronic clouds of surface sulfur atoms is considered to impede the reaction. Nitrogen introduction is one potential solution to this problem; however, the optimal ratio of sulfur to nitrogen has yet to be determined, and the enhanced reaction products that have been reported to date are limited to carbon monoxide (CO) and formic acid. In this work, copper sulfide (Cu 2 S) and copper nitride (Cu 3 N) composites with varying sulfur‐to‐nitrogen ratios are synthesized with the objective of enhancing the catalytic activity of the CO 2 reduction reaction to methane (CH 4 ). 4.20 mol% sulfur‐containing Cu 3 N exhibits a Faradaic efficiency for CH 4 production that is higher than that of all examined catalysts including bare Cu 3 N and Cu 2 S. The results of in situ Fourier‐transform infrared spectroscopy suggests that increased electron donation from the catalyst to the *CO intermediate by the introduction of sulfur into Cu 3 N shifts the selectivity of the reaction pathway from CO to CH 4 production. Taken together, the present findings demonstrate that sulfide–nitride composite structures can function as effective CO 2 reduction electrocatalysts to generate a variety of valuable products.

    Hydrogen boride (HB) nanosheets are novel 2D materials that have found application in various fields such as electronics, energy storage, and catalysis. The present study describes the novel antimicrobial effects of HB nanosheets. Transparent thin films of HB coated on a glass substrate inactivate pathogens, such as the omicron variant of SARS-CoV-2, influenza virus, feline calicivirus, and bacteriophages. The infectious titer of these microbes decreases to the detection limit within 10 min in the dark at room temperature. The antiviral function of the HB nanosheets is retained in the absence of moisture, mimicking the environment of dry surfaces. The HB nanosheets also inactivate bacteria and fungi such as Escherichia coli, Staphylococcus aureus, Aspergillus niger, and Penicillium pinophilum. We discussed the mechanism of the broad-spectrum antimicrobial function of HB nanosheets based on the physicochemical properties of HB nanosheets. Denaturation of microbial agents is derived from strong physicochemical interactions between the protein molecules in the pathogens and the surface of the HB films. The present study reports important new properties of HB nanosheets and demonstrates their utility in protecting against the spread of disease on a pandemic scale.
