In this work, we revealed a dual-pathway nonradical oxidation (NRO) system catalyzed by Ni single atom catalyst (NiN4) accommodated in the carbon nitride substrate. The monatomic coordinated with four N atoms (Ni-N4) is determined as dynamic catalytic center for peroxymonosulfate (PMS) activation, showing an exceptional specific rate constant of 3.34 min-1 g-2 L-2 (29.7 times that CN/PMS system) oxidizing bisphenol A and other refractory organics. situ Raman, X-ray absorption, electrochemical analyses well theoretical simulations demonstrate Ni-N4 sites exhibit strong interaction PMS benefited from modulated electronic structures, resulting surface-bonding active complexes (NiN4-PMS*) deuterogenic high-valent Ni(IV)-Oxo species. NRO process will spontaneously coordinate both electron transfer via CN matrix direct selective organic excellent anti-interference ability adaptability.
