One of the bottlenecks toward the successful implementation of alternative energies is the lack of methods for sustainable generation of hydrogen fuel as an energy carrier. Given that water will be at the very least an important component of the hydrogen production feedstock, sustainable catalysts are needed for the electrochemical generation of hydrogen from water. Herein, we report on the electrochemical activation of a silver-based catalyst for the efficient hydrogen evolution reaction (HER) in acidic conditions at high current densities. After activation, the catalyst is chemically and electrochemically stable over days. The starting material, silver sulfide, is synthesized by a simple and scalable chemical vapor deposition process. Upon electrochemical activation, the pristine material is converted to mesoporous silver coated with a silver oxo-sulfide layer which is highly active toward HER. Detailed microscopy and spectroscopy demonstrate the formation of both hydroxyl and sulfoxide groups on the surface of the catalyst. Interestingly, the density functional theory calculations suggest that only in the presence of these hydroxyl groups will sulfur atoms exhibit high catalytic activity with a hydrogen binding energy of −0.35 eV.

Zinc‐doped copper oxide and copper oxide nanoparticles (NPs) are synthesized and deposited on artificial teeth by sonic irradiation, and the ability of these coatings to restrict biofilm formation by Streptococcus mutans is examined. The CuO and Zn:CuO NP‐coated teeth show significant reductions in biofilm formation of 70% and 88%, respectively, compared to uncoated teeth. The mechanism of the Zn:CuO nanoparticles is investigated, revealing that the nanoparticles attach to and penetrate the bacteria and generate intracellular reactive oxygen species (ROS) that enhance lipid peroxidation and cause cell death. Conversely, the CuO or ZnO NPs do not show this behavior and could not generate intracellular ROS. These results highlight the superior efficacy of Zn:CuO nanocomposites over CuO and ZnO NPs and the role of ROS in their antimicrobial effect.
