Abstract

Graphene composites have a wide range of energy and environmental applications due to their high adsorption capacity, high carrier mobility, and stability. Therefore, it is getting more and more attention from researchers. Furthermore, photocatalytic reaction compared with the traditional catalytic reaction has the characteristics of being green, clean and having mild conditions. The application of graphene composites in the field of photocatalysis can solve many environmental pollution problems and enhance the development and utilization of new energy sources. Graphene composites as photocatalysts can play important roles in photocatalytic reduction of carbon dioxide, photocatalytic hydrogen production from water splitting and photocatalytic degradation of organic pollutants. This paper describes the preparation and advantages of graphene composites. It also summarizes the research progress of graphene composites in photocatalytic applications. Afterwards, it analyzes the drawbacks of current graphene composites as photocatalysts involved in the reaction, and provides an outlook on future directions for improving performance and reducing costs.
