Utilizing membrane separation technology has displayed promising application potential for removing synthetic dyes; however, performance tends to decline over time due fouling caused by feed solution contaminants, leading decreased efficiency and shortened lifespan. Therefore, improving the antifouling properties of membranes is critical ensure long-term water treatment systems. In this work, a high-performance catalyst, CuZn@ZC, with remarkable oxygen activation activity, was successfully prepared subsequently integrated onto surface via simple pumping filtration, resulting in self-cleaning superior capabilities. The results indicated that zero-valence copper containing CuZn@ZC can rapidly efficiently remove wide range dyes under mild natural conditions, accompanied strong 1O2 •O2– signals detected electron paramagnetic resonance spectra. When applied surfaces, modified exhibited excellent filtration properties, which showed high flux recovery ratios rejection rate cationic dyes, attributed participation ROS generated dissolved oxygen. Moreover, still retained its structural stability environmental compatibility during prolonged operation, beneficial advancing development sustainable technologies.
