Research progress of graphite phase carbon nitride-based heterogeneous structure in the field of photocatalysis
In recent years,graphite phase carbon nitride(g-C3N4)has attracted much attention in the fields of light-driven environmental and new energy catalysis due to its suitable conduction and valence band position,low cost and toxicity,visible light response,as well as good stability.However,the serious problem of photogenerated electron-hole recombination has affected the catalytic activity of g-C3 N4 in various photocatalytic reactions.The heterostructure based on g-C3 N4 has become a research hotspot in the field of photocatalysis because it can suppress the photogenerated electron-hole pair recombination and improve the photogenerated carrier utilization efficiency.This article reviews the research progress of g-C3 N4 based heterojunction in the fields of pollutant photodegradation,photocatalytic water splitting for hydrogen production and photocatalytic carbon dioxide reduction in the past five years,which can provide theoretical support for the development of g-C3 N4 based materials in the field of photocatalysis.
