In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibrating sample magnetometer (VSM) shows nanoparticles exhibit ferromagnetic behavior. The photo-catalytic behavior of MgFe2O4-ZnO nanocomposite was evaluated using the degradation of organic dyes aqueous solution under ultraviolet (UV) light irradiation. The results show that MgFe2O4-ZnO nanocomposites have applicable magnetic and photo-catalytic performance.
