Abstract

Semiconductor photocatalysis has shown great potential as a low-cost, environmentally friendly treatment technology, and has undergone various developments in relation to its energy applications. Graphene, graphene oxide, reduced graphene oxide, and heteroatom-doped graphene have stimulated interest in the design of high-performance photocatalysts for enhancing the photoefficiency of semiconductors used in solar fuel generation. This chapter summarizes the most recent advances in the fabrication and application of graphene-based semiconductor photocatalysts for solar fuel production, including photocatalytic water splitting to H2 and photocatalytic reduction of CO2 to hydrocarbon fuels. The effect of graphene and its derivatives on the photocatalytic performance of graphene-based composites is assessed and discussed. Finally, the possibilities and challenges for future research in this field are also addressed.
