Graphene oxide (GO) was incorporated to facilitate the construction of good water channels, while copper-doped manganese dioxide (Cu-MnO2) was added to enhance catalytic activity. The structure, morphology, and performance of the membranes were characterized comprehensively. Results showed that Cu-MnO2 was well interspersed between GO sheets, thereby increasing membrane surface roughness, effective filtration area, and hydrophilicity. The best catalytic membrane CM-5 exhibited the highest pure water flux (1391.20 L\u00b7m\u22122\u00b7h\u22121) and methyl blue (MBE) rejection rate (98.06%), and it also displayed excellent reusability and stability. EPR tests confirmed the generation of HO\u00b7 and HOO\u00b7 in the Fenton-like system, which mediated dye degradation. The Cu-MnO2\/GO\/PVDF catalytic membrane demonstrated excellent hydrophilicity, antifouling properties, and catalytic efficiency, thus providing a viable solution for dye wastewater treatment.<\/jats:p>","DOI":"10.3390\/membranes15120384","type":"journal-article","created":{"date-parts":[[2025,12,18]],"date-time":"2025-12-18T09:15:21Z","timestamp":1766049321000},"page":"384","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Preparation of Cu-MnO2\/GO\/PVDF Catalytic Membranes via Phase Inversion Method and Application for Separation Removal of Dyes"],"prefix":"10.3390","volume":"15","author":[{"given":"Fei","family":"Wang","sequence":"first","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Runze","family":"He","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiachen","family":"Song","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaohui","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science & Engineering, North Minzu University, Yinchuan 750021, China"},{"name":"Institute of Functional and Structural Characteristic Materials, Helanshan Laboratory, Yinchuan 750021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123488","DOI":"10.1016\/j.seppur.2023.123488","article-title":"Chemical cleaning and membrane aging of poly (vinylidene fluoride) (PVDF) membranes fabricated via non-solvent induced phase separation (NIPS) and thermally induced phase separation (TIPS)","volume":"313","author":"Yu","year":"2023","journal-title":"Sep.
