Progress of g-C_3 N_4 Material Modification and Its Photocatalytic Research

The g-materials are widely used in the photocatalytic field because of the advantages such as good stability, but they also have defects such as small specific surface area and fast electron-hole pair complexation rate that limit their applications, so it is necessary to modify the g-materials. In this paper, we study the modification methods of g-materials and their applications in the fields of photocatalytic hydrogen production, pollutant degradation, and carbon dioxide reduction, and analyze the modification methods as well as the application progress and development prospects of the materials based on the existing literature. The results show that g-can be modified with the help of doping, morphology modification and construction of heterojunction, and the modified g-materials can be better utilized in photocatalytic applications. g- materials are facing challenges in preparation, applications and theoretical innovations, and the future can be focused on improving the preparation and modification methods of g-and applying g- materials in other fields such as electrochemistry.
