英文摘要Photogenerated holes have emerged as critical mediators for activating peroxymonosulfate (PMS) in the coupled photocatalytic PMS activation system, enabling novel dual-channel activation pathway. A tandem system based on Fe-MOF@BiVO4 (Vis/PMS/Fe-MOF@BVO) with spatially separated active sites was constructed to form a dual-channel activation mechanism. The BiVO4 (010) face provides the active sites for photogenerated electrons to drive the Fe3+/Fe2+ cycle and activate PMS, while the BiVO4 (110) face serves as the active sites for photogenerated holes to activate PMS. Consequently, the Vis/PMS/Fe-MOF@BVO system achieved complete degradation of 10 mg/L BPA within 6 min, with a degradation rate constant (Kobs) of 0.74 min-1. It also demonstrated high removal efficiency for various organic pollutants with excellent immunity to interference and reusability. This work provides a new insight into the coordinative mechanism for coupled photocatalysis and PMS activation system.
