Abstract
As a visible light responding polymer and semiconductor photocatalyst,graphitic carbon nitride(g-C3N4)has the advantages of cheap and readily available,chemically stable,non-toxic and harmless,as well as having suitable band gap and band positionetc. However,g-C3N4 can only absorb light shorter than 460nm and its photogenerated carriers recombine severely,which has restricted its application. Modification of g-C3N4 is an effective means to improve its photocatalytic ability. This article outlines the structure,properties and preparation methods of g-C3N4,then focuses on the research progress of g-C3N4,including morphology controlling,compounding with semiconductors,element doping,molecular doping and dye-sensitized. It also discusses the applications of g-C3N4 in pollutants removal,hydrogen evolution,CO2 reduction and other aspects of organic synthesis. The prospects for the development of g-C3N4 based photocatalysts are also discussed,and the research direction of graphitic carbon nitride are proposed as multiple modification,application and mechanism exploration.关键词
