This paper presents a photochemical synthesis method for producing pure CeO2 2 deposits and CeO2 2 deposits loaded with varying proportions of Fe2O3. 2 O 3 . The deposits were calcined at 950 degrees C and characterized structurally, compositionally, and morphologically using XRD, XPS, SEM, FT-IR, and Raman spectroscopy techniques. Cerianite and hematite phases were identified in CeO2/Fe2O3 2 /Fe 2 O 3 samples, indicating heterogeneous surface deposits. Photocatalytic testing under UV-Vis illumination for 5 h demonstrated promising results. For the degradation of bright green dye, efficiencies of 78.9 % and 90.1 % were achieved for pure CeO2 2 and CeO2 2 samples loaded with 1.0 mol% Fe2O3, 2 O 3 , respectively. Similarly, for oxytetracycline drug degradation, performance rates of 35.3 % and 67.0 % were observed for CeO2 2 and CeO2 2 samples loaded with 1.0 mol% Fe2O3, 2 O 3 , respectively. Recyclability tests showed a gradual decline in photocatalytic performance over successive cycles due to by-product accumulation contaminating the catalyst.
