Fe-based heterogeneous catalytic advanced oxidation processes show great potential for treating wastewater. However, catalyst instability often hinders their practical use, mainly due to the slow regeneration of Fe2+ sites. Herein, we developed a Fe3S4/WO3 catalyst, where electron-rich Wx and Sx sites promoted efficient electron transfer, enabling continuous active on surface. The exhibited outstanding degradation efficiency tetracycline (TC) in peroxymonosulfate (PMS) system, achieving 92.5% removal efficiency, significantly higher than its individual components Fe3S4 (52.8%), WO3 (43.1%), WS2 (53.2%). Moreover, Fe3S4/WO3/PMS system demonstrated broad operational pH range (3.0–9.0), excellent various emerging pollutants, minimal interference from background electrolytes organic matter, strong stability real water treatment. Chemical scavenger tests paramagnetic resonance (EPR) analysis confirmed that oxidative TC was driven by multiple reactive species, including SO4•−, •OH, •O2−, 1O2. This study provides novel strategy regulating catalysts ensure sustained performance, offering pathway rational design next-generation Fenton-like sustainable micropollutant
