摘要

: 六价铬对环境有长期的危险性，人体摄入可能造成遗传性基因缺陷甚至癌症。目前光催化降解六价铬被认为是一种廉价而快速的方法，C3N4 是一种具有平面形的类石墨烯材料，具有良好的光催化性能，通过复合铜锌锡硫( Cu2ZnSnS4 ) ，得到了具有优异降解性能的复合材料，在5 min 时降解率达到了95.2%，相较于单一的C3N4和Cu2ZnSnS4 分别提升了4.83 和 1.4 倍。

Abstract:

Hexavalent chromium poses long-term environmental risks and can cause genetic defects and even cancer in humans，whereas trivalent chromium does not．At present，photocatalytic degradation of hexavalent chromium is considered as a cheap and rapid method． C3N4 is a planar graphene-like material with good photocatalytic performance．By composite copper，zinc，tin and sulfur ( Cu2ZnSnS4 ) ，the composite material with excellent degradation performance was obtained，and the degradation rate reached 95．2% at 5 min．Compared with the single C3N4 and Cu2ZnSnS4，the increase was 4．83 and 1．4 times．

Key words: photocatalytic hexavalent chromium degradation composite materials
