摘　　要：与Fenton、类Fenton、UV/H2O2以及均相Photo-Fenton体系相比,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。非均相Photo-Fenton反应体系的关键问题是催化剂问题。着重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研究发展概况,对目前光催化剂存在的一些问题以及未来发展方向进行了总结与展望。Compared with Fenton, Like-Fenton, UV/H20z and homogeneous Photo-Fenton reaction system, the heterogeneous Photo-Fenton reaction system shows a big potential because of its advantages such as high reaction efficiency, a wide range of pH and renewable catalyst. The key problem of heterogeneous Photo-Fenton reaction system is the catalyst. In this paper, some new research progress in preparation and application of supported catalysts in heterogeneous Photo-Fenton reaction system are introduced in detail in recent years. At last, some problems which exist presently are put forward, and the prospect about Photo-catalyst is made.
