This study focuses on synthesizing mixed oxides Cu\u2013Mn\u2013O with different ratios and coating the optimal onto a PET membrane using a dip\u2010coating method. The materials were thoroughly characterized through FTIR, XRD, TGA, zeta potential, EDS, BET, and SEM. The 3:1CuO\/MnO\n                    <jats:sub>2<\/jats:sub>\n                    showed a low\u2010order structure and seems to be amorphous through XRD results. SEM results showed that the mixed oxide nanoparticles have a porous structure, ultra\u2010small size, and uniform distribution. The large specific surface area of the 3:1CuO\/MnO\n                    <jats:sub>2<\/jats:sub>\n                    (64.09\u2009m\n                    <jats:sup>2<\/jats:sup>\n                    \/g) enhances the surface\u2010active sites. In adsorption and degradation tests, the 3:1CuO\/MnO\n                    <jats:sub>2<\/jats:sub>\n                    consistently showed the highest efficiency for both Congo red (CR) and methylene blue (MB). Specifically, the CR degradation reaction followed pseudo\u2010second\u2010order kinetics (PSO), while the MB degradation process conformed to pseudo\u2010first\u2010order kinetics (PFO). In membrane filtration, the water flux reached 170.5\u2009L\/m\n                    <jats:sup>2<\/jats:sup>\n                    .h for the PET membrane and decreased to 124.7\u2009L\/m\n                    <jats:sup>2<\/jats:sup>\n                    .h for the 3:1CuO\/MnO\n                    <jats:sub>2<\/jats:sub>\n                    \/PET membrane due to the filling of the catalytic particles. Notably, the CR rejection of the 3:1CuO\/MnO\n                    <jats:sub>2<\/jats:sub>\n                    \/PET membrane surged from 74.3% to 96.7% in the presence of peroxydisulfate (PDS). ROS (reactive oxygen species) trapping tests identified singlet oxygen as the primary oxidizing agent. Finally, the catalytic membrane exhibited impressive durability with stable performance after 4\u2009cycles, opening up potential practical applications in textile wastewater treatment.\n
