Abstract Cu‐doped ZnO nanoparticle‐loaded cellulose nanofiber membranes are investigated for their potential photocatalytic and antibacterial properties. nanoparticles, both undoped doped with copper, synthesized by the co‐precipitation process, afterward immobilized onto nanofibers through utilization of a dip‐coating technique. Methylene blue (MB) removal is evaluated to inspect effectiveness photocatalysts in UV Xenon lighting conditions. The morphology structure composite loaded then examined using FE‐SEM, TEM, XRD, FTIR, UV–vis characterizations. Under visible light, self‐cleaning effects organic compounds measured, presenting more than 50% discoloration various stains. activity assessed Kirby–Bauer disc diffusion method plate counting against gram‐positive Staphylococcus aureus (S. aureus) gram‐negative Escherichia coli (E. coli) bacteria. current study shows that coated nanoparticles exhibited excellent activities.
