Fe3O4/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 Fe3O4 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-2 h-1 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 Fe3O4/PVDF three-channel hollow fiber catalytic membrane was a promising alternative for the degradation of organic contaminants.

Fe3O4 / PVDF催化膜处理有机废水，同时提高了渗透性，催化性能和防污性能。

Fe3O4 /聚偏氟乙烯（PVDF）三通道中空纤维催化膜是通过非溶剂诱导的相转化成功制备的，并用于有机废水的降解。分别通过场发射扫描电子显微镜（SEM），水接触角和热重分析（TGA）表征了Fe3O4纳米颗粒的添加对催化膜的表面和截面形态，亲水性和热性能的影响。所获得的催化膜表现出良好的亲水性，通过Fenton催化反应具有175.8 L m-2 h-1的高纯水通量和高的亚甲基蓝去除率（高达97.6％）。同时，由于存在芬顿反应，催化膜表现出优异的防污性能。
