Recycling of photocatalyst in wastewater treatment is a big challenge. Fixation of photocatalyst on a flexible surface of solid substrates is a promising solution. In this work, copper ferrite (CuFe₂O₄) particles were loaded onto polydopamine (pDA) pretreated ceramic/polyester fabrics (CPF) via coprecipitation. The CPF not only acts as loading material for CuFe₂O₄ particles, but also makes this photocatalyst convenient to recycle. The morphology, elemental composition and structure of the as-fabricated CPF/CuFe₂O₄ were characterized by scanning electron microscope (SEM), Fourier transform Infrared (FT-IR) spectrometer, X-ray photoelectron spectroscopy (XPS) and X-ray diffractometer (XRD). The degradation rate of methylene blue (MB) by the CPF/CuFe₂O₄ photocatalyst reached to 98.2% under visible light irradiation for 80 min, reflecting the excellent photocatalytic activity of the composites. The CPF/CuFe₂O₄ demonstrated good photostability and recoverability, indicating its great potential in wastewater treatment. Moreover, the degradation mechanism and possible degradation pathway of MB by CPF/CuFe₂O₄ photocatalyst were investigated.

在废水处理中回收光催化剂是一个很大的挑战。将光催化剂固定在固体基材的柔性表面上是一种很有前景的解决方案。在这项工作中，通过共沉淀将铁氧体铜 (CuFe ₂ O ₄ ) 颗粒负载到聚多巴胺 (pDA) 预处理的陶瓷/聚酯织物 (CPF) 上。CPF不仅充当CuFe ₂ O ₄颗粒的负载材料，而且使该光催化剂便于回收。制备的 CPF/CuFe ₂ O ₄的形貌、元素组成和结构通过扫描电子显微镜（SEM）、傅里叶变换红外（FT-IR）光谱仪、X射线光电子能谱（XPS）和X射线衍射仪（XRD）对其进行表征。CPF/CuFe ₂ O ₄光催化剂对亚甲基蓝（MB）的降解率在可见光照射80分钟后达到98.2%，体现了复合材料优异的光催化活性。CPF/CuFe ₂ O ₄表现出良好的光稳定性和可回收性，表明其在废水处理中的巨大潜力。此外，研究了CPF/CuFe ₂ O ₄光催化剂对MB的降解机理和可能的降解途径。
