Abstract:
With rapid global industrialization, environmental pollution has become one of the major problems of human society. Photocatalysis can be applied to solve environmental problem by using inexhaustible solar energy. As a novel two-dimensional material, graphite carbon nitride (g-C 3 N 4 ) has been widely applied in many photocatalytic reactions. However, in terms of its practical applications, g-C 3 N 4 still has limitations, including poor photoexcited charge separation, limited range of visible light absorption, and low surface areas. Hence, current research on g-C 3 N 4 mainly focuses on improving its photocatalytic performance. In this review, we summarize various methods to improve g-C 3 N 4 ’s light absorption and photo-induced charge transfer, including vacancy engineering, morphology control, heteroatom doping, and forming heterostructure. The applications of g-C 3 N 4 and its derivatives in photodegradation of organic pollutants are also discussed in detail. Finally, the challenges and future research directions of g-C 3 N 4 photocatalysts are summarized to promote their environmental applications. Graphical Abstract
