类芬顿催化剂研究进展

Research Progress of Fenton-like Catalysts

随着我国对于环境质量要求的不断提高,亟需有效的方法来处理工业进程中产生的有毒有害且难降解的有机污染物。类芬顿由于其低成本、操作简单以及对环境无污染等特点,近年来备受关注。研究的重点在于开发出成本低、普适性强、效果明显的催化材料。本文介绍了类芬顿反应催化剂的种类有单金属/金属氧化物、多金属/金属氧化物,以及金属+螯合物体系等,综述了类芬顿降解污染物常见类型分别为染料、酚类化合物、PPCPs及其它有机污染物,并介绍了相关的研究进展,同时对该类催化剂的研究方向进行了展望。

With the increasing demand of the quality of environment in China, an effective solution must be found to deal with the hazardous and hardly degradable organic pollutants produced during the industrial process. In recent years, Fenton-like processes have attracted increasing interest due to its low cost, simply operation and not having second pollution etc.. The focus of the study is to obtain a catalytic materials with low cost, universality and efficient. In this paper, the types of Fenton＇s reaction catalysts are described as single metal / metal oxides, polymetallic / metal oxides, and metal ＋ chelate systems. The common types of Fenton-degrading pollutants are dyes, phenols, PPCPs and other organic pollutants. This paper introduced the relevant research progressand the research direction of these catalysts was also discussed.
