Comparison of Photo Degradation Efficiency of Ce/Fe/TiO₂ Composite Catalyst Under UV and Visible Light Towards Evans Blue Dye

Abstract

This study investigates the synthesis and photocatalytic performance of a Ce/Fe/TiO₂ composite catalyst supported on nano carbon (NC), designated as Ce/Fe/TiO₂@NC, for the degradation of EB dye. The composite was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM), which confirmed the successful incorporation of cerium, iron, and titanium dioxide in the NC matrix. XRD analysis revealed distinct peaks corresponding to the anatase phase of TiO₂, cerium oxide, and iron, indicating the formation of the composite. The photocatalytic activity of Ce/Fe/TiO₂@NC was evaluated under both UV and visible light irradiation, showing significant dye degradation, with 90.91% degradation under UV light at a dye concentration of 20 mg/L. The results suggest that Ce/Fe/TiO₂@NC is a highly efficient photocatalyst for organic pollutant degradation, offering potential applications in environmental remediation and wastewater treatment.
