摘　　要：活化过硫酸盐的高级氧化技术(SR-AOPs)在降解有机污染物方面效果优异且成本低廉,成为了现阶段的研究重点。钴基双金属催化剂是由两种不同的金属组成,比单金属催化剂的催化性能更好,可以有效活化过一硫酸盐(PMS),转换成硫酸盐自由基。本文阐述了钴镍催化剂、钴锌催化剂、钴铜催化剂和钴铁催化剂活化PMS降解有机污染物的机理,以及钴基双金属催化剂的几种方法。最后,提出了该技术现在面临的问题及其发展方向,并就未来的发展进行了展望。The advanced oxidation technology(SR-AOPs)of activated persulfate has excellent effect and low cost in the degradation of organic pollutants and has become the focus of current research.Cobalt-based bimetallic catalysts are composed of two different metals,which have better catalytic performance than single-metal catalysts and can effectively activate peroxymonosulfate(PMS)and convert it into sulfate radicals.The mechanisms of cobalt-nickel catalyst,cobalt-zinc catalyst,cobalt-copper catalyst,cobalt-iron catalyst and cobalt-manganese catalyst are described to degrade organic pollutants.This article introduces several methods for cobalt-based bimetallic catalysts.Finally,the problems facing the technology and its development direction are put forward,and the future development is prospected.
