The Mn–Co dual-metal oxide is recognized as an effective activator for peroxymonosulfate (PMS), but its activation mechanism remains controversial. In this study, a Co/Mn–C–N (CMCN) nanocatalyst was synthesized using simple pyrolysis method, and catalytic activity along with the PMS comprehensively explored. findings indicated that synergistic effect of Mn Co within bimetallic composition significantly enhanced efficiency CMCN compared to those individual metal oxides (Mn–C–N Co–C–N). Bisphenol A underwent successful degradation 3 min in neutral environment, kinetic rate 1.59 min–1 total organic carbon removal 63.8%. Moreover, nanoparticles demonstrated remarkable stability reusability, maintaining their efficacy over four cycles. Employing series experiments analytical characterizations, novel proposed, involving both radical nonradical pathways. This involves oxidation pollutants through direct electron transfer process from metastable intermediate complexes. Notably, CMCN/PMS system exhibited robust resistance interference factors. research provides insights into development composites recalcitrant water pollutants.
