Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

Carbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Anchoring Monolayer TiOx Nanosheets on Gold Nanoparticles Enhances Catalytic Activity for CO Oxidation Depending on the Type of Support

Chemistry – A European Journal, EarlyView.
Monolayer TNS cover Au/SiO2 and Au/CeO2 surfaces, forming Au–TiOx contact structure that serve as active sites for CO oxidation, thereby significantly improving catalytic activity. On Au/SiO2, the Au–TiOx interface was generated through TNS adsorption and calcination, while TNS adsorption solely promoted the Au–TiOx interface formation on Au/CeO2.
