A polysulfone/metal–organic framework (MOF) based photocatalytic nanofiltration membrane is proposed in this study. Interfacial   polymerization (IP)   is   the universal method of preparing   nanofiltration   (NF)   membranes. In this work, the (TFN)   membranes   were   synthesized   with   an in-situ interfacial synthetic   method   to incorporate BiOCl/MIL-101(Fe)@PDA(BMP)   into the polyamide (PA) selective   layer. Five distinct BMP loadings (0, 0.05, 0.1, 0.15, and 0.2 wt%) were established to examine the impact of additional BMP on the physicochemical characteristics of the produced TFN membranes. Under the irradiation of a xenon lamp with a power of 300 W, the water flux of M3 at a pressure of 0.6 MPa was 277.14 L m -2 h -1 . Furthermore, the BSA-based antifouling tests demonstrated the membrane’s outstanding antifouling capabilities, with a flux recovery rate reaching 94.08 %. The optimal membrane maintained a high and stable retention of tetracycline for 12 h. The interfacial synthesis of MOF/PA offers a new approach to the fabrication of photocatalytic NF membranes.
