FeO/Polyvinylidene fluoride (PVDF) three-channel hollow fiber catalytic membrane was successfully fabricated via non-solvent induced phase inversion and used for organic wastewater degradation in this work. The effects of FeO nanoparticles addition on the surface and cross-section morphologies, hydrophilicity and thermal properties of the catalytic membrane were characterized by the field emission scanning electron microscopy (SEM), water contact angle and thermogravimetric analysis (TGA), respectively. The obtained catalytic membrane exhibited good hydrophilicity, a high pure water flux of 175.8 L m h and a high removal of methylene blue (up to 97.6%) with Fenton catalytic reaction. Meanwhile, the catalytic membrane shows excellent anti-fouling property due to the presence of Fenton reaction. Our results show that FeO/PVDF three-channel hollow fiber catalytic membrane was a promising alternative for the degradation of organic contaminants.
FeO/聚偏二氟乙烯（PVDF）三通道中空纤维催化膜通过非溶剂致相转化法成功制备，并在这项工作中用于有机废水降解。通过场发射扫描电子显微镜（SEM）、水接触角和热重分析（TGA）分别研究了 FeO 纳米粒子的添加对催化膜表面和横截面形态、亲水性和热性能的影响。所得催化膜具有良好的亲水性，在芬顿催化反应中纯水通量高达 175.8 L·m-2·h-1，对亚甲基蓝的去除率高达 97.6%。同时，由于存在芬顿反应，催化膜表现出优异的抗污染性能。我们的结果表明，FeO/PVDF 三通道中空纤维催化膜是降解有机污染物的一种很有前途的选择。
