摘要
石墨相氮化碳(g-C_(3)N_(4))基复合结构形成后,能够有效避免光生载流子的复合,从而提高光催化反应活性,通过光催化合成反应产生超氧自由基,并能够降解芳香烃类含苯环的有机物。该文概述了石墨相氮化碳的结构和性质,重点介绍了石墨相氮化碳与贵金属、金属氧化物和复合氧化物半导体、碳材料等的复合结构,并探讨了石墨相氮化碳微纳米复合材料的光催化机理。
After the graphite phase carbon nitride(g-C_(3)N_(4))based composite structure is formed,it can effectively avoid the recombination of photogenerated carriers,thus improving the photocatalytic activity.Through the photocatalytic synthesis reaction,superoxide radicals are generated,which can degrade organics such as aromatic hydrocarbons containing benzene ring.In this paper,the structure and properties of graphite phase carbon nitride are summarized.The composite structures of graphite phase carbon nitride with noble metals,metal oxides and composite oxide semiconductors,carbon materials,etc.are emphatically introduced.And the photocatalytic mechanism of g-C_(3)N_(4)composites is discussed.
