Synthesis of g-C3N4 based S-type heterojunction and its photocatalytic property
Semiconductor-based photocatalytic technology was selected as a"green"sustainable solution for envi-ronmental remediation and energy storage with solar energy.In this paper,the advantages and limitations of g-C3N4,as well as the advantages and disadvantages of S-type semiconductors are first introduced,then the elec-tronic structure and photocatalytic properties of g-C3N4-based S-type heterojunction photocatalytic materials are introduced.Then the strategies with which to improve the photocatalytic performance of S-type heterojunction photocatalytic materials based on different types of g-C3N4 are reviewed,and some of their applications are re-viewed.Finally,this review gives the challenges and future development trends of S-heterojunction based on g-C3N4,which is expected to provide important references for the development and practical application of g-C3N4-based S-heterojunction photocatalytic materials.
