Abstract：The visible-light responsive photocatalytic composite ultrafiltration membranes were prepared by L-S phase inversion method, where polysulfone (PSF) was used as membrane material and the hydrophilic Fe-doped TiO2 nanoparticles were additive. In addition, surface morphology, surface functional groups, hydrophilicity, ultrafiltration performance, mechanical property, thermal stability and photocatalytic performance were separately analyzed to explore the influences of Fe-TiO2 on the composite membrane. The results showed that when the mass ratio of Fe-TiO2 and PSF was 0.20, the RhB removal rate of Fe-TiO2/PSF composite membrane (61%) was evidently higher than that of pure PSF membrane (33%). By adding photocatalyst, the composite membrane could possess response under simulated solar irradiation. Meanwhile, a certain amount of catalyst could improve the physical and chemical properties of PSF membrane, which broadens its application field.
