Synthesis,Modification and Application of Photocatalytic Material Graphite Phase Carbon Nitride
Graphite phase carbon nitride(g-C3N4),as an environmentally benign semiconductor material,has good application prospects in photocatalysis.However,the disadvantages of pure g-C3N4 such as small specific surface area and difficult separation of photogenerated carriers will limit its photocatalytic performance,which will restrict its large-scale application.From the synthetic methods and modification strategies,the research progress of g-C3N4 photocatalysts by researchers in recent years is reviewed,and the development of g-C3N4 photocatalysts in the fields of degradation of pollutants in water treatment,H2 and H2O2 production is summarised,and it can be found that the performance of the modified g-C3N4 photocatalysts has been greatly improved.Finally,the development direction of g-C3N4 photocatalyst is prospected.
