Chlorophenols are difficult to degrade and mineralize by traditional advanced oxidation processes due the strong electronegativity of chlorine. Here, a dual-site atomically dispersed catalyst (FeMoNC) is reported, which Fe/Mo supported on mesoporous nitrogen-doped carbon prepared through high-temperature migration. The FeMoNC exhibits high dechlorination rate 93.3% within 1 min. Theoretical calculation suggested that doping high-valence Mo6+ as electron reservoir, promoted electronic delocalization at Fe sites, thereby enhancing adsorption dissociation peroxymonosulfate (PMS), subsequent generation (IV) = O singlet oxygen (1O2) species. An interesting finding Mo sites can adsorb chlorine in 4-chlorophenol (4-CP) induce C─Cl bond fracture. Thus, FeMoNC/PMS system has catalytic performance synergistic effects Mo-induced non-radical species (Fe(IV) 1O2) degradation pathways, efficiency 99.1% 4-CP 5 min without significant decline after 168 h ≈15,120-bed volumes. These findings advance mechanistic understanding PMS activation molecular level guide rational design efficient eco-friendly single-atom catalysts (SACs) with bimetallic atomic sites.
