Rapid generation of high-valent cobalt-oxo species (Co(IV)═O) for the removal organic contaminants has been challenging because low conversion efficiency Co(III)/Co(II) and high activation energy barrier Co(II)-oxidant complex. Herein, we introduced nitrogen (N) vacancies into graphite carbon nitride imbedded with cobalt carbonate (CCH/CN–Vn) in a peroxymonosulfate (PMS)/visible light system to break limitations conventional two-electron transfer path. These N enhanced electron distribution Co 3d orbital lowered cleave O–O bond PMS Co(II)-PMS complex, achieving modulation major active from 1O2 Co(IV)═O. The developed synergistic that exhibited adsorption oxidation showed remarkable selectivity contaminant performance inorganic (Cl–, NO3–, HCO3–, HPO4–) (HA) even practical aqueous matrices (tap water secondary effluent). This study provides novel mechanistic perspective modulate nonradical path refractory treatment via defect engineering.

Fenton-like catalysis based on peroxymonosulfate (PMS) activation has shown great potential in the treatment of organic wastewater. Heterogeneous catalysts containing transition metal active sites are highly efficient for PMS activation. However, reduction oxidized was usually not prompt due to sluggish reaction kinetics, which caused insufficient redox cycle and further hampered efficiency. Recent studies have that synergy effect between photocatalysis may address above obstacle boost overall a deeper understanding this is still missing, making it difficult be rationally controlled; thus, poor frequently reported. Herein, Co/Fe bimetal-doped graphitic carbon nitride (g-C3N4) designed representatively through systematical characterization theoretical calculation, revealed profoundly determined by competitive role hole system adsorbed metastable PMS* catalyst surface, furthermore, can manipulated; when doping ratio 2.5:2.5, as-prepared g-C3N4 with moderate valence band position endow an optimized photo-Fenton-like synergistic highest catalytic degradation performance. This work sheds light rational design catalysts.
