摘要
Excellent photocatalytic properties for hydrogen production in water splitting under simulated solar light (with AM1.5G filter) with Au nanoparticles (NPs)/Zn Cd S nanowires (NWs) have been demonstrated. The Zn Cd S NWs photocatalyst shows much higher photocatalytic activity for H -production than ZnS and CdS NWs with Na S and Na SO as sacrificial reagents. The high photocatalytic H -production activity, as high as 57.07 mmol g h , is attributed to appropriate band gap width and suitable conduction band edge potential of the Zn Cd S NWs. The H -production efficiency was further significantly enhanced to 96.04 mmol g h by decorating Zn Cd S NWs with appropriate size and distribution of Au NPs to induce localized surface plasmon resonances (LSPR) in visible and near infrared region. The work represents significant advance with a totally green and novel approach of enhancing H -production efficiency in water splitting under simulated solar light (with AM1.5G filter).
