The assembly of vanadium(iv)-substituted Keggin-type polyoxometalate/graphene nanocomposite and its application in photovoltaic system†
Abstract
SiW11V/graphene nanocomposite was first prepared and introduced into TiO2 film. It showed a significant photocurrent response, which can be attributed to the photoinduced electrons of SiW11V. This work provides a promising strategy for exploring POMs sensitizers with lower energy levels than the CB of TiO2.
