Novel self-cleaning catalytic membranes are prepared for water treatment via an integration of heterogeneous Fenton and membrane process. Polysulfone (PSF) based functional copolymers with pendant ferrocene groups are facilely synthesized via a combination of controlled radical polymerization and ester coupling reaction. Different catalytic membranes with tuned surface hydrophilicity are then prepared through non-solvent phase inversion method based on functional ferrocene- and hydroxyl-containing PSF. These membranes have demonstrated high activity in catalyzing Fenton-type reactions, which also lead to outstanding antifouling performance for the membrane. Finally, the catalytic membranes are successfully used for treatment of waste water containing different dyes. The proposed strategy in this work may provide worthy guidance to catalytic membranes, which is promising for water purification through simultaneous Fenton reaction and membrane separation.

通过将非均质Fenton和膜工艺相结合，制备了用于水处理的新型自清洁催化膜。具有侧链二茂铁基团的聚砜（PSF）基功能共聚物可通过以下方法轻松合成受控自由基聚合和酯偶联反应的结合。然后通过基于功能性二茂铁和羟基的PSF的非溶剂相转化方法，制备了具有不同表面亲水性的催化膜。这些膜在催化Fenton型反应中显示出高活性，这也导致该膜具有出色的防污性能。最后，催化膜已成功用于处理含有不同染料的废水。这项工作中提出的策略可能为催化膜提供有价值的指导，这对于通过同时进行的Fenton反应和膜分离进行水净化很有希望。
