Graphene-Based Photocatalysts for Hydrogen Generation

Graphene-based photocatalysts have gained increasing interest as a viable alternate to increase photocatalytic H-2 production performance in converting solar energy into chemical energy. The use of graphene to enhance the efficiency of photocatalysts has been proved due to its unique two-dimensional conjugated structure and electronic properties. In this Perspective, we have summarized the recent significant advances on the design and applications of graphene-based photocatalytic composites. The rational designs for high-performance photocatalysts using graphene-based materials are described. The applications of the new materials in photocatalytic hydrogen evolution are presented. Finally, the ongoing challenges and opportunities for the future development of graphene-based photocatalysts are also proposed.
