摘　　要：随着工业的迅速发展,含有大量难降解有机污染物的生活生产废水被排入水体,对人体健康与环境产生严重威胁。基于过硫酸盐的高级氧化技术在处理难降解有机废水上有着突出表现,而采用单原子催化剂能最大限度地利用金属原子,减少金属离子溶出,在活化过硫酸盐降解有机污染物中有很好的应用前景。综述了单原子催化剂的制备方法,并阐述了各种方法的优缺点。分别论述了Fe、Co、Mn和Cu等金属单原子催化剂活化过硫酸盐降解有机污染物的应用,并总结了单原子催化剂活化过硫酸盐的机理以及单原子催化剂活化过硫酸盐体系对有机污染物的降解机理。最后对单原子催化剂活化过硫酸盐降解有机污染物未来的发展做出了讨论及展望。With the rapid development of industry,large amount of refractory organic pollutants in domestic and in⁃dustrial wastewater are discharged into water bodies,posing a serious threat to human health and the environment.Advanced oxidation processes(AOPs)based on persulfates have shown outstanding performance in treating refrac⁃tory organic wastewater,and the use of single-atom catalysts(SACs)can maximize the utilization of metal atoms and reduce the leaching of metal ions,which has a promising application prospect in the activation of persulfates for the degradation of organic pollutants.The preparation methods of single-atom catalysts were summarized,and the advan⁃tages and disadvantages of various methods were discussed.The application of single-atom catalysts with metals such as Fe,Co,Mn and Cu in the activation of persulfates for the degradation of organic pollutants was discussed.The mechanisms of single-atom catalysts in activating persulfates and the degradation mechanisms of the persulfate system catalyzed by single-atom catalysts towards organic pollutants were summarized.Finally,the future develop⁃ment of single-atom catalysts in activating persulfates for the degradation of organic pollutants was discussed.
