Research progress in preparation and application of non-metal-doped g-C3N4 photocatalytic materials

Abstract

With the continuous research on the basic theory and application technology of photocatalysis, certain progress has been made in the understanding of the preparation, performance mechanism and application aspects of new photocatalysts driven by visible light. Graphitic phase carbon nitride(g-C3N4), as a chemically stable non-metallic material, has attracted much attention from domestic and foreign scholars because of its environmental friendliness and high plasticity. In recent years, the exploration and application of g-C3N4 based materials in the field of photocatalysis have been developed rapidly. Among them, the strategy of doping non-metallic elements was particularly prominent, which has become a research hotspot in materials science and environmental chemistry and other disciplines.In order to sort out and summarize the relevant researches in a timely manner, the current research status of non-metal-doped modified g-C3N4-based photocatalytic materials in recent years was summarized and reviewd in this paper, the preparation methods of non-metal-doped g-C3N4 and its applications in photocatalysis was systematically discussed, and an outlook was presentd on its future development direction, such as the applicontion of photoatalysis, photothermal catalysis, and piezoelectric photocatalysis, which will the further explored.
