Global industrialization has intensified the emission of emerging contaminants (ECs), posing a serious threat to environment and human health. Persulfate-based advanced oxidation processes (PS-AOPs) have become research hotspot due their efficient degradation capability environmentally friendly features; carbon-based materials are ideal catalysts for activating persulfate (PS) tunable electronic structure, abundant active sites, low cost. This study summarizes application (graphene, single-atom (SACs), etc.) in PS-AOPs, provides insights into mechanisms radicals (e.g., sulfate radical (SO4−·), hydroxyl (·OH)) non-radicals 1O2(singlet oxygen), electron transfer). The removal efficacy antibiotics, phenols, dyes was compared, key pathways were elucidated. In addition, activation PS can be accelerated, catalytic efficiency improved by synergizing with ancillary technologies light, electricity). Despite great potential catalysts, large-scale is limited complexity catalyst preparation process lack selectivity complex water qualities. Future studies accelerate practical PS-AOPs wastewater treatment through precise design SACs construction multi-mechanism synergistic systems.
