摘　　要：当前水环境污染已成为全球性普遍关注的重要课题,而利用光催化氧化技术处理水中难降解有机污染物的方法己经引起了国内外水处理专家的广泛关注。自1907年由A.Braun教授和T.C.Tcherniac教授第一次发现酞菁化合物以来,有关利用酞菁化合物对水中污染物进行光催化降解的研究备受瞩目。酞菁化合物由于具有18π电子体系的共轭结构,能吸收可见光区的光,因而显现出独特的光电特性。对酞菁化合物可见光催化降解水中有机污染物研究现状进行了综述,分别介绍了酞菁化合物的典型结构及其特性,并对其催化降解有机污染物反应机理进行阐述,总结了近年来酞菁化合物在降解水中有机污染物方面的应用,从环境可持续发展角度来看,具有十分重要的意义。Nowadays, water environment pollution has become a common concern in the world. The photocatalyric oxidation as a good wastewater treatment technique is getting more and more attention. Since the phthalocyanine compound was first discovered by Professor A. Braun and Professor T. C. Tcherniac, many studies have been conducted on the photocatalytic degradation of refractory pollutants in sewage. Phthalocyanine compounds, with 18-re-electron conjugated structure, can absorb visible light and show the unique photoelectronic properties. The researches on the degradation of organic pollutants in sewage catalyzed by phthalocyanine compounds under visible light are re- viewed, the structure and property of phthalocyanine compounds are analyzed, the reaction mechanisms of the catalytic degradation are mentioned as well. At last, the applications of phthalocyanines in degradation of organic pollutants are generalized, which is of great significance for the sustainable development of environment.
