Abstract
AbstractThe localized surface plasmonic resonance (LSPR) excitation in plasmonic nanoparticles is showing great promise in solar‐driven chemical conversions, known as plasmon‐induced catalysis. In exploring its enormous potential, constructing multicomponent structure with both LSPR absorption and catalytic active parts is an ideal way, while most studies are limited to metallic core‐shell structure. Herein, hybrid nanostructure with plasmonic metal oxide (MoO2) and catalytic Pt nanoclusters is successfully designed. Under illumination, it not only demonstrates to be highly active for the preferential oxidation of CO in the presence of H2 (CO‐PROX) but also shows a dramatically wide temperature range for the total conversion of CO. The pathway of plasmon‐energy decay in MoO2 is clarified to selectively dissipate through catalytically active Pt sites in the form of hot carriers, thereby inducing efficient chemical transformation. These results may open an avenue in exploring plasmonic metal oxide materials to drive and modulate plasmon‐induced catalysis under illumination.
