Molecular-level insight into photocatalytic CO2 reduction with H2O over Au nanoparticles by interband transitions

Abstract

While plasmonic metals show some activity for photocatalysis, they often must be paired with semiconductors or sacrificial reagents. Here, authors find quantum-sized Au nanoparticles can achieve photocatalytic CO2-to-CO conversion with H2O by charge carriers generated from interband transitions.
