The peroxymonosulfate (PMS)-triggered radical and nonradical active species can synergistically guarantee selectively removing micropollutants in complex wastewater; however, realizing this on heterogeneous metal-based catalysts with single sites remains challenging due to insufficient electron cycle. Herein, we design asymmetric Co-O-Bi triple-atom Co-doped Bi2O2CO3 facilitate PMS oxidation reduction simultaneously by enhancing the transfer between sites. We propose that result an density increase Bi decrease Co sites, thereby undergoes a reaction generate SO4•- •OH at site 1O2 site. suggest synergistic effect of SO4•-, •OH, enables efficient removal mineralization without interference from organic inorganic compounds under environmental background. As result, achieves almost 99.3% sulfamethoxazole degradation 3 min k-value as high 82.95 min-1 M-1, which is superior existing reported so far. This work provides structural regulation approach control catalytic function, will guide rational Fenton-like catalysts.

Abstract Simultaneous regulation of the coordination environment single‐atom catalysts (SACs) and engineering architectures with efficient exposed active sites are strategies for boosting peroxymonosulfate (PMS) activation. We isolated cobalt atoms dual nitrogen oxygen (Co−N 3 O 1 ) on oxygen‐doped tubular carbon nitride (TCN) by pyrolyzing a hydrogen‐bonded cyanuric acid melamine–cobalt acetate precursor. The theoretically constructed Co−N moiety TCN exhibited an impressive mass activity 7.61×10 5 min −1 mol high 2 selectivity. Theoretical calculations revealed that single occupied environment, PMS adsorption was promoted energy barriers reduced key *O intermediate produced . were attached to widely used poly(vinylidene fluoride) microfiltration membrane deliver antibiotic wastewater treatment system 97.5 % ciprofloxacin rejection over 10 hours, thereby revealing suitability industrial applications.

Single oxygen-based advanced oxidation processes (1O2-AOPs) exhibit great prospects in selective degradation of organic pollutants. However, efficient production 1O2 via tailored design catalysts to achieve contaminants remains challenging. Herein, we develop a simple strategy regulate the components and coordination Co–N–C at atomic level by adjusting Zn/Co ratio bimetallic zeolitic imidazolate frameworks (ZnxCo1-ZIFs). Zn4Co1–C demonstrates 98% removal phenol mixed phenol/benzoic acid (phenol/BA) solutions. Density functional theory calculations experiments reveal that more active CoN4 sites are generated Zn4Co1–C, which beneficial peroxymonosulfate activation generate 1O2. Furthermore, correlation between origin selectivity well-defined is systematically investigated electron paramagnetic resonance test quenching experiments. This work may provide novel insights into target pollutants complicated water matrix.
