非均相Photo—Fenton反应体系具有反应效率高、有效pH范围宽广以及催化剂可再生利用等优势,是一项极具发展潜力的新型高级氧化工艺。本文简单介绍了近几年来有关非均相Photo—Fenton体系中负载型光催化剂的最新研究成果,主要包括以SiO2、Al2O3、分子筛、碳基材料、黏土材料等无机载体,以及以离子交换树脂和有机纤维材料等有机载体制备的负载型光催化剂,并且在此基础上着重讨论了光催化机理。对目前非均相Photo—Fenton反应存在的一些问题以及未来发展方向作了总结与展望。
Heterogeneous Photo-Fenton reaction system displays a great potential because of its advantages such as high reaction efficiency, a wide range of pH and renewable catalyst. This paper firstly introduced some new research progress of some catalysts supported inorganic carriers(SiO2, Al2O3, zeolite, carbon materials and clay materials) and organic materials (ion-exchange resin and organic fiber) in heterogeneous Photo-Fenton reaction system in recent years, and on this basis, related photocatalysis reaction mechanism were discussed in detail. At last, some present problems were put forward, and the prospect about heterogeneous Photo-Fenton reaction system was simply made.
