Single-atom catalysts (SACs) are a promising area in environmental catalysis. We report on bimetallic Co–Mo SAC that shows excellent performance activating peroxymonosulfate (PMS) for sustainable degradation of organic pollutants with high ionization potential (IP > 8.5 eV). Density Functional Theory (DFT) calculations and experimental tests demonstrate the Mo sites – Co SACs play critical role conducting electrons from to sites, leading 19.4-fold increase rate phenol compared CoCl 2 PMS group. The exhibit catalytic even under extreme conditions show long-term activation 10-d experiments, efficiently degrading 600 mg/L phenol. Moreover, catalyst has negligible toxicity toward MDA-MB-231, Hela, MCF-7 cells, making it an environmentally friendly option water treatment. Our findings have important implications design efficient remediation other applications biology medicine.
