Abstract

The Fe₃O₄/SiO₂/TiO₂ nanocomposite has been prepared by coating magnetite core particles with silica and photoactive titania using sono-coprecipitation and sol-gel methods followed by microwave assisted synthesis. The nanocomposite was characterized by X-ray diffraction, infrared spectroscopic analysis, diffuse reflectance spectroscopy and transmission electron microscopy. Results showed that the product is Fe₃O₄ crystal coated with SiO₂ and TiO₂. Transmission electron microscopy image showed that core-shell structure of Fe₃O₄/SiO₂/TiO₂ has been produced. The prepared photocatalyst presented good photocatalytic activities for the degradation of methylene blue under UV irradiation. The Fe₃O₄/SiO₂/TiO₂ nanocomposite could be easily recovered by the application of external magnetic field for reuse.
