Application of Graphene and Its Derivative Materials in the Field of Photocatalytic Hydrogen Production

Abstract

Graphene is a single-atom-thick two-dimensional (2D) carbon material, which exhibits excellent electrical conductivity, high electron mobility, large specific surface area, superior optical transmittance, and outstanding chemical stability. These inherent properties endow it with great suitability for photocatalytic applications. In practical photocatalytic research, graphene is commonly modified according to the catalytic conditions, catalyst composition, and target properties to be exploited; alternatively, graphene derivatives such as graphene oxide (GO) are adopted. Benefiting from the remarkable optoelectronic properties of graphene and its derivatives, they hold broad application prospects in the field of photocatalytic hydrogen evolution (PHE). Furthermore, with the in-depth understanding of their structure and properties, their role in the field of photocatalytic hydrogen evolution will be further consolidated and enhanced. Herein, we review the advances in the application of graphene and its derivatives in photocatalytic hydrogen evolution in recent years, and provide an outlook on their future development trends.
