摘要:

电(类)Fenton技术作为一种高级氧化技术,已经成为难降解有机废水处理领域的研究热点。其可通过阴极曝气的方式原位持续在线生成双氧水(H2O2),并与电极表面或溶液中的催化剂反应生成羟基自由基(·OH),实现污染物的高效降解。因此,阴极材料的研发是该技术的关键。综述了电(类)Fenton阴极材料的国内外研究现状及其在水处理中的应用,重点比较了其原位电生成H2O2的能力和存在的优缺点等,并对未来的发展趋势进行了阐述。

Abstract:

Electro-Fenton-like technology, as an advanced oxidation technology, has become a hot topic in the field of biorefractory organic wastewater treatment. It can electro producing hydrogen peroxide(H2O2) in situ via the oxygen reduction reaction on the cathode, which react with the catalyst on the electrode surface or at the solution to produce hydroxyl radicals(·OH) to obtain the degradation of organic pollutants. Hence, the research and development of cathode materials are crucial for this technology. The recent progress of electro-Fenton-like cathode materials and their application in wastewater treatment were reviewed. The ability of electro producing in situ H2O2 and their advantages and disadvantages were emphatically described, and then the development trends for electro-Fenton-like cathode were also prospected.

Key words: electro-Fenton-like, cathode, hydrogen peroxide, hydroxyl radical
