Abstract

In this research, magnetite NPs via sol/gel method was coated with ZnO and TiO2. Phases, microstructures, and magnetic properties of binary and Ternary core/shell Nanoparticles were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrational magnetometer (VSM). Photocatalytic activities in methylene blue degradation under sunlight irradiation for 120 min were recorded using UV/Vis spectrophotometer, changes were studied using the photoluminescence spectrum (PL), and the specific surface areas were obtained by the nitrogen adsorption/desorption apparatus (BET). The results showed that 10 mg/ml core/ shell Nanoparticles during 120 min under sunlight radiation could degrade >90% of methylene blue molecules. However, the increase in the number of shells causes the change in the type of semiconductors from direct to indirect; following that heterogeneous interface reduces the photocatalytic efficiency.
