Abstract

Single-atom catalysts (SACs) have attracted extensive attention from researchers due to their maximum atomic utilization, unique geometric configuration, and excellent activity and selectivity in a variety of catalytic reactions. In this review, the application of SAC-activated peroxymonosulfate (PMS) or peroxydisulfate (PDS) degradation of organic pollutants is summarized, including new synthesis methods and characterization techniques for SACs, as well as two mechanisms of activated PMS/PDS radical and nonradical degradation of organic compounds, and the future research directions such as updating new synthesis methods, development of multi-atomic catalysts and development of high-performance transition metals are proposed. In addition, the mechanism of SAC activation of PMS/PDS for the degradation of organic pollutants is analyzed and discussed in a relatively comprehensive way. Overall, this catalytic pathway has great prospects in aquatic environment remediation.

单原子催化活化PMS/PDS降解水环境中有机污染物的机理综述

单原子催化剂因其最大的原子利用率、独特的几何构型以及在多种催化反应中优异的活性和选择性而受到广泛关注。本文综述了活性炭活化过氧单硫酸盐(PMS)或过氧二硫酸盐(PDS)降解有机污染物的应用，包括活性炭的新合成方法和表征技术，以及活性PMS/PDS自由基和非自由基降解有机化合物的两种机制，以及未来的研究方向，如更新新的合成方法;提出了多原子催化剂和高性能过渡金属的发展方向。此外，对SAC活化PMS/PDS降解有机污染物的机理进行了较为全面的分析和探讨。综上所述，该催化途径在水生环境修复中具有广阔的应用前景。

期刊介绍： The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
