Abstract

Binary co-catalysts of Pt and Cu2 O with a core-shell structure significantly enhance the photocatalytic reduction of CO2 with H2 O to CH4 and CO. The Cu2 O shell provides sites for the preferential activation and conversion of CO2 , whereas the Pt core extracts the photogenerated electrons from TiO2 . The deposition of Cu2 O shell on Pt nanoparticles markedly suppresses the reduction of H2 O to H2 .
