The studies on the origin of versatile oxidation pathways toward targeted pollutants in single-atom catalysts (SACs)/peroxymonosulfate (PMS) systems were always associated with coordination structures rather than perspective pollutant characteristics, and analysis mechanism commonality is lacking. In this work, a variety (M-SACs, M: Fe, Co, Cu) fabricated via pyrolysis process using lignin as complexation agent substrate precursor. Sixteen kinds commonly detected various references selected, their ln k obs values M-SACs/PMS correlated well ( R 2 = 0.832 to 0.883) electrophilic indexes (reflecting electron accepting/donating ability pollutants) energy gap 0.801 0.840) between complexes. Both transfer (ETP) radical can be significantly enhanced systems, while was overwhelmed by ETP lower indexes. contrast, higher represented weaker electron-donating capacity complexes, which resulted accompanied noticeable oxidation. addition, different regulated gaps complexes pollutants. As result, Fenton-like activities could modulated reaction pathways, determined both sites. This work provided strategy establish PMS-based AOP tunable capacities for high-efficiency organic decontamination.
