Abstract: As an eco-friendly catalytic material, carbon-based catalyst can effectively eliminate undesirable leaching and secondary pollution of toxic metal ions. This review describes the scope of recent advances on the use of different carbon-based materials, such as activated carbon, graphene, carbon nanotubes, mesoporous carbon, nanodiamonds, biochar as catalyst to activate persulfate(PDS) to degrade organic pollutants, provides insight into the selectivity and degradation efficiency of different carbon-based materials on organic pollutants, and the issues of various carbon-based materials that existed are briefly summarized. Subsequently，the effects of different doping and modification contributing to the catalytic activity are evaluated. Three reaction mechanisms existing in carbon-based catalysts activating persulfate to degrade organic pollutants are elaborated simultaneously, and the following perception relative to advantages and disadvantages of radical and nonradical mechanism are given. This paper proposes a carbon-catalyst regeneration method based on the issue of poor stability and reusability of carbon-based catalysts. Ultimately，we give the prospect for carbon catalyst used to activate PDS to degrade organic contaminants in actual wastewater.

摘要： 碳基催化剂作为一种绿色催化材料，可以有效防止有毒金属离子的浸出和二次污染。本文首先对使用不同碳基材料（包括活性炭，石墨烯，碳纳米管，中孔碳，纳米金刚石，生物炭）作为催化剂活化过二硫酸盐（PDS）降解有机污染物的研究进展进行了梳理，比较了不同碳基材料对有机污染物的选择性和降解效果，并对各种碳基材料存在的问题进行了总结；然后探讨了碳基催化剂掺杂改性对催化活性的影响，并对碳基催化剂活化过二硫酸盐降解有机污染物存在的三种反应机制进行了具体的阐述，对自由基机制和非自由基机制的优缺点进行了对比和讨论；通过对碳基催化剂存在稳定性和重复利用性差的问题提出了碳催化剂再生方法，最后对碳催化剂用于活化PDS降解实际有机废水的前景做出展望。
