In this paper, a high-performance composite nanofiber membrane with excellent air filtration and dye degradation properties was prepared by incorporating MIL-53 (Fe) nanoparticles into the electrospinning solution. The results showed that the filtration efficiency for PM2.5 of the PP/FVDF-HFP/MIL-53(Fe) composite nanofiber membrane reached up to 99.3% with the addition of 2 wt% MIL-53(Fe). Moreover, the composite nanofiber membrane exhibited steady filtration efficiency across different parameters, including air velocity, PM2.5 concentration, and extended testing time. Furthermore, the incorporation of MIL-53(Fe) significantly enhanced the removal efficiency of the composite nanofiber membrane toward Rh B, resulting in a remarkable 91% removal rate. The polymer/MOF composite nanofiber membranes prepared by simple and cheap electrospinning technology have a wide range of practical applications in the field of environmental protection.
