摘要
钴基催化剂活化过一硫酸盐(PMS)具有催化活性高、操作简便、易回收和成本较低等优点,因此近年来在高级氧化技术领域备受关注。综述了钴基催化剂的典型合成方法,包括固相法、气相法和液相法等;介绍了用于活化PMS的钴基催化剂的类型,包括具有特殊形貌的钴氧化物、负载型钴氧化物和钴基复合金属氧化物;阐述了钴基催化剂活化PMS在环境修复中降解有机染料、内分泌干扰物以及药物和个人护理品的研究进展;总结了目前钴基催化剂活化PMS存在的一些不足,并对该领域今后的研究提出了展望。
The activation of peroxymonosulfate(PMS)by cobalt‐based catalysts has the advantages of high catalytic activity,simple operation,easy recyclability,and low cost.Hence,it has attracted much attention in the field of advanced oxidation processes in recent years.This paper reviewed typical methods for the synthesis of cobalt‐based catalysts,including solid phase,gas phase,and liquid phase methods.Several types of cobalt‐based catalysts for PMS activation,including cobalt oxides with special morphologies,supported cobalt catalysts,and cobalt‐based composite metal oxides,were summarized.The applications of these cobalt‐based catalysts in environmental remediation via PMS activation were also elaborated,such as the degradation of organic dyes,endocrine‐disrupting chemicals,and pharmaceutical and personal care products.Finally,the current shortcomings of cobalt‐based catalysts in PMS activation were summarized,and some future research directions in this area were proposed.
