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.
