摘      要：Semiconductor heterojunction photocatalysts have received much concern due to their great application prospect in solar energy utilization and *** construction of heterostructure with two or more semiconductor materials can integrate the advantages of multi-components to simultaneously improve the photo-induced charges separation,extend visible light absorption range and retain the high redox ability of ***,constructing of g-C3 N4-based heterostructure has become a hot focus due to the multiple merits of g-C3 N4,such as facile synthesis,high stability,unique optical and electronic *** review tries to give a comprehensive introduction and provide the possible tendency in design and fabrication of g-C3 N4-based heterojunction photocatalysts,especially in rational synthesis of type-II heterojunction,direct Z-scheme heterojunction,new type of S-scheme heterojunction,p-n heterojunction and Schottky ***,the special charges transfer mechanisms of g-C3 N4-based heterojunctions are discussed and their potential applications in photocatalytic water splitting,photo-degradation of contaminants and photo-reduction of CO2 into fuels are also ***,we attempt to propose some crucial issues based on the current research,which should be further investigated and resolved in this interesting research area.
