Fenton-like activity and pathway modulation via single-atom sites and pollutants comediates the electron transfer process.

ABSTRACT: The studies on the origin of versatile oxidation pathways toward targeted pollutants in the single-atom catalysts (SACs)/peroxymonosulfate (PMS) systems were always associated with the coordination structures rather than the perspective of pollutant characteristics, and the analysis of mechanism commonality is lacking. In this work, a variety of single-atom catalysts (M-SACs, M: Fe, Co, and Cu) were fabricated via a pyrolysis process using lignin as the complexation agent and substrate precursor. Sixteen kinds of commonly detected pollutants in various references were selected, and their lnk_obs values in M-SACs/PMS systems correlated well (R² = 0.832 to 0.883) with their electrophilic indexes (reflecting the electron accepting/donating ability of the pol
