This paper reports the successful synthesis of spinel‐type CuFe 2 O 4 ferrite nanoparticles with an average particle size 24 nm, produced using citrate sol–gel autocombustion method. The structure synthesized material was analyzed through x‐ray diffraction (XRD) and further supported by Raman FT‐IR spectroscopy. analysis confirmed that formed a spinel Fd3m space group. Valence states energy levels elements were examined photoelectron spectroscopy (XPS). Surface morphology studied scanning electron microscopy (SEM), coupled elemental analysis. magnetic properties investigated vibrating sample magnetometer (VSM). Magnetization measurements revealed exhibited characteristic parameters copper ferrite, saturation magnetization (Ms) 23.10 emu/g, coercivity Hc 415 Oe, remnant (Mr) 12.80 emu/g. These enable efficient separation from aqueous solutions, thereby enhancing process efficiency minimizing catalyst loss during photocatalytic applications. Optical spectrophotometry, revealing optical band gap 1.85 eV, which demonstrates potential for activity under visible light. effectively degraded dyes such as methylene blue (MB), malachite green (MG), Safranine (S), Congo Red (CR), Rhodamine B (RhB) within 180 min, highlighting its practical application potential. study identified hydroxyl radicals (·OH), generated H decomposition light irradiation, played critical role in photo‐Fenton reaction. A proposed mechanism involves excitation light, facilitating transfer leads to generation ·OH radicals, degrade dye molecules. Among tested dyes, CR highest degradation percentage rate constant 0.033 min⁻ 1 followed pseudo‐first‐order kinetic model. effect hydrogen peroxide concentration on also evaluated.
