Heterogeneous photo-Fenton systems offer efficient solutions for the treatment of wastewaters in the textile industry. This study investigated the fabrication and structural characterization of novel peculiar-shaped Cu II O, Fe III  2 O 3 , and Fe II O nanoparticles (NPs) compared to the properties of the iron(II)-doped copper ferrite Cu II  0.4 Fe II  0.6 Fe III  2 O 4 . The photocatalytic efficiencies of these NPs and the composite of the simple oxides (Cu II O/Fe II O/Fe III  2 O 3 ) regarding the degradation of methylene blue (MB) and rhodamine B (RhB) as model dyes were also determined. The catalysts were synthesized via simple co-precipitation and calcination technique. X-ray diffractometry (XRD), scanning electron microscopy (SEM), and diffuse reflectance spectroscopy (DRS) were utilized for structural characterization. The structure of Cu II O was bead-like connected into threads, Fe III  2 O 3 was rod-like, while Fe II O pallet-like, with average crystallite sizes of 18.9, 36.9, and 37.1 nm, respectively. The highest degradation efficiency was achieved by Cu II O for RhB and by Cu II  0.4 Fe II  0.6 Fe III  2 O 4 for MB. The Cu II O/Fe II O/Fe III  2 O 3 composite proved to be the second-best catalyst in both cases, with excellent reusability. Hence, these NPs can be successfully applied as heterogeneous photo-Fenton catalysts for the removal of hazardous pollutants. Moreover, the simple metal oxides and the iron(II)-doped copper ferrite displayed a sufficient antibacterial activity against Gram-negative Vibrio fischeri .
