Preparation, Characterization and Photocatalytic Activity of Multifunctional Fe₃O₄/ZnO/CuO Hybrid Nanoparticles

Abstract:

A series of copper oxide supported on Fe₃O₄/ZnO with molar ratio of Fe₃O₄:ZnO:CuO varies from 1:1:1 to 1:1:5 were prepared by sol-gel method. X-ray diffraction, field emission scanning electron microscope, energy-dispersive X-ray spectroscopy, UV-visible diffuse reflectance spectroscopy and vibrating sample magnetometer were used to characterize the as prepared Fe₃O₄/ZnO/CuO hybrid nanoparticles. The results show that Fe₃O₄/ZnO/CuO hybrid nanoparticles consist of cubic spinel Fe₃O₄, hexagonal wurtzite ZnO and monoclinic CuO. All prepared samples show ferromagnetic behavior. The photocatalytic activities of these hybrid nanoparticles under visible light irradiation were evaluated by the degradation of malachite green. The results revealed that hybrid nanoparticles exhibited higher photocatalytic activities than pure nanoparticles.
