dc.description.abstractTHIS PAPER PRESENTS A PHOTOCHEMICAL SYNTHESIS METHOD FOR PRODUCING PURE CEO2 DEPOSITS AND CEO2 DEPOSITS LOADED WITH VARYING PROPORTIONS OF FE2O3. THE DEPOSITS WERE CALCINED AT 950 °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 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 AND CEO2 SAMPLES LOADED WITH 1.0 MOL% FE2O3, RESPECTIVELY. SIMILARLY, FOR OXYTETRACYCLINE DRUG DEGRADATION, PERFORMANCE RATES OF 35.3 % AND 67.0 % WERE OBSERVED FOR CEO2 AND CEO2 SAMPLES LOADED WITH 1.0 MOL% FE2O3, RESPECTIVELY. RECYCLABILITY TESTS SHOWED A GRADUAL DECLINE IN PHOTOCATALYTIC PERFORMANCE OVER SUCCESSIVE CYCLES DUE TO BY-PRODUCT ACCUMULATION CONTAMINATING THE CATALYST.
