Abstract Singlet oxygen ( 1 O 2 ) has attracted great attention owing to its superior comprehensive oxidizing performance and extensive application in dealing with ever‐growing environmental pollution. However, the efficient catalytic generation of is very challenging due low activity most catalysts oxygen‐containing radicals reaction. Herein, C‐doped Co nanoparticles (CoNPs) supported on porous carbon (C─Co/C) as highly reactive selective ‐producing are demonstrated for oxidation recalcitrant organics via activation peroxymonosulfate (PMS). The doped C 2p orbitals can accept 3d electrons, thereby weakening Co─O bonding between PMS or other intermediates such *SO 4 , *OH, *OOH, *O. adsorption cleavage energy nanoparticle reduced from 8.09 4.64 eV by doping. barrier *OOH step also lowered significantly, kinetically improving . C─Co/C promotes 100% high modified kinetic model K values 457.0 94.5 µmol s −1 g rhodamine (RhB) 2,4‐dichlorophenol (2,4‐DCP), respectively.

In this study, CoFe2O4 anchored by MoS2 modified biochar (CoFe2O4@MoS2-BC) was synthesized using a hydrothermal approach and utilized to activate peroxymonosulfate (PMS) degrade rhodamine B (RhB). The effects of pH value, catalyst PMS dosage, RhB concentration, coexisting compounds were systematically investigated. Within 7 min, CoFe2O4@MoS2-BC achieved removal rate 99.63% for 100 mg·L-1 RhB. outstanding stability environmental compatibility verified cycling metal ion leaching experiments. contribution 1O2, SO4•-, •OH, •O2- in the degradation procedure revealed quenching experiments, among which 1O2 predominant active species. Electrochemical characterization indicated that exhibited enhanced current density, redox activity, superior electron transfer capability. Comprehensive analysis experimental data high efficiency attributed Co2+/Co3+, Fe2+/Fe3+, Mo4+/Mo6+ on surface. cycles Co2+/Co3+ Fe2+/Fe3+ Mo, while unsaturated S increased reactivity thereby accelerating ions; oxygen vacancies (Ov) enhance mobility surrounding ions promoted conversion from lattice (Olat) reactive species (O*), activating effectively. This research is expected provide innovative insights will inform design development excellent activity heterogeneous metal-based catalysts.
