Abstract：photocatalytic water splitting into hydrogen has broad application prospects in solving energy shortage and environmental problems. In recent years, carbon materials have shown great potential in improving photocatalytic hydrogen production of semiconductor photocatalysts. This paper reviews the research progress of carbon nanotubes (CNT), graphene, fullerene and other carbon materials in improving the performance of semiconductor photocatalysts. In order to improve the photocatalytic hydrogen production efficiency of carbon based photocatalytic materials, the researchers started from the surface chemical functionalization, the doping effect, and the interface between semiconductor and carbon materials.Carbon materials play a role including supporting materials, increasing adsorption and active sites, electron acceptors, and transport channels. Finally, the paper summarizes the whole paper and puts forward the prospect of the development of carbon-based photocatalytic materials in the future.
