The ubiquity of refractory organic matter in aquatic environments necessitates innovative removal strategies. Sulfate radical-based advanced oxidation has emerged as an attractive solution, offering high selectivity, enduring efficacy, and anti-interference ability. Among many technologies, sulfite activation, leveraging its cost-effectiveness lower toxicity compared to conventional persulfates, stands out. Yet, the activation process often relies on transition metals, suffering from low atom utilization. Here we introduce a series single-atom catalysts (SACs) employing metals g-C3N4 substrates, effectively activating for acetaminophen degradation. We highlight superior performance Fe/CN, which demonstrates degradation rate constant significantly surpassing those Ni/CN Cu/CN. Our investigation into electronic spin polarization characteristics these reveals their critical role catalytic efficiency, with oxysulfur radical-mediated reactions predominating. Notably, under visible light, activity is enhanced, attributed increased generation radicals strengthened electron donation-back donation dynamic. proximity Fe/CN's d-band center Fermi level, alongside polarization, shown improve adsorption reduce HOMO-LUMO gap, thereby accelerating photo-assisted activation. This work advances understanding SACs environmental applications lays groundwork future water treatment technologies.
