Abstract

The precise construction and tuning of metal–support interfaces remain a significant challenge in catalyst design. Here, we developed a Pt/PtO_x/TiO₂ catalyst with an epitaxial spreading structure using an interfacial compatibility strategy. Stable interfacial PtO_x species and abundant oxygen vacancies form efficient synergistic active centers, enhancing the RWGS reaction.
