Synthesis of Fe۳O۴/ ZnO/CuO Nanocomposite and their Sono-photocatalyst Property for Removal of Methylene Blue from Wastewater

Fe۳O۴/ZnO/CuO nanocomposites with various molar ratios of CuO were successfully synthesized. Sol-gel method was used to syntehesize nanocomposite materials at a low temperature. A set of experiments, including X-ray diffraction (XRD), Dynamic Light Scattering (DLS), scanning electron microscopy (SEM), and UV-Vis spectroscopy, was used to confirm the successful synthesis of Fe۳O۴/ZnO/CuO nanocomposites in crystalline form. The photocatalytic activity of the samples was investigated via the degradation of methylene blue (MB) dye from synthetic wastewater under three distinct conditions: visible light, ultraviolet light, and a combination of visible light with ultrasonic treatment. Fe۳O۴/ZnO/CuO nanocomposite with a molar ratio of ۱:۱:۰.۵ showed the highest photocatalytic activity when irradiated with either visible or ultraviolet light. Furthermore, when visible light was combined with ultrasonic treatment, complete (۱۰۰%) removal of methylene blue was achieved within ۱۲۰ minutes. The results demonstrate that these nanocomposites are efficient catalysts for wastewater treatment through the removal of organic pollutants Fe۳O۴/ZnO/CuO nanocomposites with various molar ratios of CuO were successfully synthesized.
