摘要

石墨相氮化碳(g-C3N4)具有特殊的能带结构和稳定的物理化学性能,可通过光照分解水产氢,但由于光生电子-空穴复合严重以及禁带宽度限制等问题,对于光的利用非常有限。将g-C3N4与其他光催化材料复合,可以降低电子-空穴的复合率并且拓宽吸收范围,从而提高光催化活性。介绍了g-C3N4复合材料的光催化产氢机理,综述了g-C3N4复合材料的制备方法及产氢性能,展望了未来g-C3N4复合材料的发展方向。

Abstract

Graphite-phase carbon nitride (g-C3N4) can be used to produce hydrogen by photolysis of water because of its unique band structure and stable physical and chemical properties.However,due to its serious photoelectron-hole combination and the limitation of the band gap width,the utilization of light is very restricted.Compositing g-C3N4 with other photocatalysts can reduce the electron-hole recombination rate and broaden the absorption range,thereby improving photocatalytic activity.In this paper,the mechanism of photocatalytic hydrogen production of g-C3N4 composite materials was introduced,the preparation methods and hydrogen production performance of g-C3N4 composites were reviewed,and the future development directions of g-C3N4 composites were prospected.
