Interfacial facet engineering on the Schottky barrier between plasmonic Au and TiO2 in boosting the photocatalytic CO2 reduction under ultraviolet and visible light irradiation

Hybrid photocatalytic nanostructures composed of plasmonic metal and wide-band-gap semiconductor components have been widely developed, in which metal not only acts as a cocatalyst to trap the photogenerated electrons from semiconductor for improved charge separation and provide highly active sites for accelerated reaction kinetics, but also serves as a light-harvesting antennae to extend the light absorption region based on the injection of...
