Abstract The activation of persulfates to degrade refractory organic pollutants is a hot issue in advanced oxidation right now. Here, it reported that single‐atom Fe‐incorporated carbon nitride (Fe‐CN‐650) can effectively activate peroxymonosulfate (PMS) for sulfamethoxazole (SMX) removal. Through some characterization techniques and DFT calculation, proved Fe single atoms Fe‐CN‐650 exist mainly the form Fe‐N 3 O 1 coordination, exhibited better affinity PMS than traditional 4 structure. degradation rate constant SMX Fe‐CN‐650/PMS system reached 0.472 min −1 , 90.80% still be degraded within 10 after five consecutive recovery cycles. radical quenching experiment electrochemical analysis confirm are by two non‐radical pathways through 2 Fe(IV)═O induced at sites. In addition, intermediate products show toxicity attenuation or non‐toxicity. This study offers valuable insights into design carbon‐based catalysts provides potential remediation technology optimum disintegrate pollutants.

Abstract Advanced Oxidation Processes (AOPs) are promising for treating persistent pollutants, yet challenges arise due to the step-wise oxidants activation process, which traditional single-active-center catalysts struggle facilitate effectively. Recently, dual-active-center have emerged as a solution by enabling synergistic reactions. This review covers advances in these catalysts, their co-catalytic mechanisms, and applications electro-Fenton, photocatalytic, peroxymonosulfate-, pollutant-as-electron-donor based Fenton-like processes, along with active site design considerations future challenges.
