Reserch progress of phenols degradation with Fenton catalyst supported on porous materials

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.
