非均相负载型Fenton催化剂材料设计合成研究进展

New Research Progress in Development of Heterogeneous Fenton Supported Catalyst

由于国家在经济和社会建设上的大力发展和人口的不断增加,污水排放量也屡创新高,而对排放污水的不当处理会造成不同程度的环境污染。作为高级氧化技术的一种,绿色芬顿(Fenton)催化氧化法能产生具有强氧化能力的羟基自由基(·OH)等活性基团,氧化体系中的有机污染物。与传统方法相比,其具有条件温和、氧化速率快、对氧化对象无选择性等优点。另外由于非均相Fenton催化技术的发展解决了目前均相Fenton反应存在的问题,因而成为水处理领域的研究热点。综述了近几年有关非均相Fenton催化剂载体的研究,旨在寻找使Fenton催化剂能发挥更好的催化效果的载体。

Due to the vigorous development of country in economic and social construction and the increasing population, sewage discharges have also hit record highs. Improper disposal of discharged sewage will cause different levels of environmental pollution. As a kind of advanced oxidation technology, the green Fenton catalytic oxidation method can generate active groups such as hydroxyl radicals(·OH) with strong oxidizing ability and organic pollutants in the oxidation system. Compared with the traditional method, it has the advantages of mild conditions, fast oxidation rate and no selectivity to oxidized objects. In addition, due to the development of heterogeneous Fenton catalytic technology, the problem of the current homogeneous Fenton reaction is solved, which has become a research hotspot in the field of water treatment. In this paper, the research on heterogeneous Fenton catalyst carrier in recent years is reviewed, aiming at finding a carrier that can make Fenton catalyst play a better catalytic effect.
