    • Nitrogen doped TiO2 (N—TiO2) is used to fabricate Poly(vinyledene fluoride) (PVDF)/N—TiO2 mixed matrix hollow fiber membranes (HFMs) through a phase inversion method to improve filtration efficiencies and antifouling properties. The membranes performances were evaluated based on the water permeability, humic acid (HA) rejection and antifouling properties. Resulting membranes showed brown color and improved hydrophilicity, especially under light irradiation. When compared to original PVDF and PVDF/P25 membrane, mixed matrix membranes containing N—TiO2 nanoparticles (NPs) showed clear photocatalytic activities under visible light irradiation. Also, membrane performance assessments indicated that PVDF/N—TiO2 membranes possessed enhanced water flux, similar HA rejection (e.g., above 96%) and improved fouling resistance with PVDF membranes as a control. The results demonstrate the potential of the suggested methodology for development of membranes with improved water permeability and superior antifouling properties based on photo-degradation processes and photo-induced hydrophilicity enhancement driven by solar light as a renewable energy source.
    • 氮掺杂TiO2(N-TiO2)用于通过相转化法制备聚(氟乙烯)氟化物(PVDF)/ N-TiO2混合基质中空纤维膜(HFM),以提高过滤效率和防污性能。 膜性能基于透水性,腐殖酸(HA)排斥和防污性能进行评估。 所得膜显示褐色和改善的亲水性,特别是在光照射下。 与原始PVDF和PVDF / P25膜相比,含有N-TiO2纳米粒子(NP)的混合基质膜在可见光照射下显示出明显的光催化活性。 此外,膜性能评估表明,PVDF / N-TiO2膜具有增强的水通量,类似的HA排斥(例如高于96%),并且以PVDF膜作为对照改善了耐污垢性。 结果表明了基于光降解过程和由太阳光作为可再生能源驱动的光诱导亲水性增强的改进的水渗透性和优异的防污性质的膜的开发方法的潜力。
