摘　　要：多孔载体负载型非均相Fenton催化技术是近年来发展起来的一种处理有机污染物的有效手段,因其克服了均相Fenton催化体系存在的受pH值限制大、含铁污泥产生量大、Fe3+还原为Fe2+速率缓慢等问题,近年来备受研究者的重视。本文扼要介绍了自2000年以来国内外关于以多孔载体(黏土、沸石、介孔氧化硅及多孔碳)负载型Fenton催化剂降解酚类污染物的研究进展,特别指出了未来该类催化剂降解有机物的发展方向为:进一步提高催化剂的稳定性和中性条件下催化剂的活性、延长催化剂的使用寿命、开发新型多孔材料载体。Porous materials supported Fenton catalysis is an effective approach to degrading organic pollutants developed in recent years. It has been a topic of interest for researchers,because it can resolve the problems of homogeneous Fenton system,such as being limited by pH,bringing about large amounts of sludge and slow rate of reducing Fe3＋to Fe2＋. This paper presents an overview of phenols degradation with Fenton catalyst supported on clay,zeolite,mesoporous silica and porous carbon since 2000. More work needs to be done in improving reactivity under neutral condition and stability of catalyst,prolonging the lifetime of catalyst and developing new porous material as support.
