Nonradical Fenton-like catalysis offers an opportunity to degrade extracellular antibiotic resistance genes (eARGs). However, high-loading single-atom catalysts (SACs) with controllable configurations are urgently required selectively generate high-yield nonradicals. Herein, we constructed Fe SACs (5.4-34.2 wt %) uniform Fe-N4 sites via optimized coordination balance of supermolecular assembly for peroxymonosulfate activation. The selectivity singlet oxygen (1O2) generation and its contribution eARGs degradation were both >98%. This targeting strategy oxidizing guanines low ionization potentials by 1O2 allowed 7 log within 10 min eliminated their transformation 2 min, outperforming most reported advanced oxidation processes. Relevant interactions between revealed at a single-molecule resolution. exhibited excellent universality stability different water matrices. These findings provide promising route constructing efficient selective treatment.
