文摘

Au/Ag-NPs-modified TiO2 NWs investigated for selective CO2 reduction to fuels. Synergistic effects in Au-Ag alloy contributed to enhance TiO2 NWs photo-activity. The yield of CO over Au-Ag/TiO2 NWs was 73 fold more than the bare TiO2 NWs. Enhanced activity was due to LSPR effect, more light absorption and electron sink. Quantum yield and TOP were significantly enhanced in Au/Ag-NPs/TiO2 NWs.
