Fenton or Fenton-like technique, as one of the advanced oxidation processes, plays a significant role in the removal of non-easily degradable organic pollutants; however, most of such catalysts are fragile with poor structural integrity under large deformation, thereby restricting their wide applications. Herein, soft copper ferrite nanostructures functionalized silica nanofibrous membranes (CuFe₂O₄@SNM) were fabricated through a novel strategy with the combination of in-situ dopamine polymerization, ion adsorption, and cohesive precipitation method. Benefiting from the high metallic ion adsorption capacity of polydopamine together with the rapid co-precipitation of adsorbed ions on fiber surface in alkaline solution, the membranes possessed homogenously distributed nanostructured CuFe₂O₄, large specific surface area, and high pore volume, which are a benefit for the improvement of Fenton-like catalytic activity towards organic pollutants decomposition. The resultant soft CuFe₂O₄@SNM provided favorable catalytic performance towards organic pollutants with a relatively high degradation degree of 96% in 20 min, a fast removal rate of 0.148 min⁻¹, and outstanding recyclability. The successful preparation of such fascinating ceramic nanofibrous membranes would provide a reference for further exploitation of new type Fenton or Fenton-like catalysts with outstanding softness towards wastewater purification.

Fenton或类似Fenton的技术，作为一种先进的氧化过程，在去除不易降解的有机污染物方面起着重要作用。然而，大多数这样的催化剂在大变形下易碎且结构完整性差，从而限制了它们的广泛应用。在这里，软铜铁氧体纳米结构功能化的二氧化硅纳米纤维膜（CuFe ₂ O ₄（SNM）是通过结合原位多巴胺聚合，离子吸附和内聚沉淀法的新型策略制备的。得益于聚多巴胺的高金属离子吸附能力以及碱性条件下纤维表面吸附离子的快速共沉淀，该膜具有均匀分布的纳米结构CuFe ₂ O ₄，比表面积大和孔体积大等优点。有助于改善Fenton样对有机污染物分解的催化活性。生成的软质CuFe ₂ O ₄@SNM提供了对有机污染物的良好催化性能，其在20分钟内的相对较高的降解度为96％，快速去除速率为0.148 min ^-1，并且具有出色的可回收性。这种引人入胜的陶瓷纳米纤维膜的成功制备将为进一步开发新型的Fenton或类Fenton催化剂提供参考，该催化剂对废水的净化具有出色的柔软性。
