Abstract

In this study, Fe3O4 / SiO2 / TiO2 composite was prepared with core-shell-SHELL STRUCTURE using a wet chemical method. At first the composite Fe3O4 / SiO2 was synthesized via Tetraethyl orthoSILICAte (TEOS) precursor. Then a shell of TiO2 was coated directly on it. Fe3O4 / SiO2 / TiO2 microstructures produced were characterized by environmental scanning electron microscopy analysis (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy devices (FTIR). The results showed that SiO2 and TiO2 layers has been coating successfully. The results indicated that the mean size of Fe3O4 particles was about 300-400 nm and thickness of the TiO2 and SiO2 shells was about 4 and 30 nm, respectively. magnetic properties of the synthesized composite were studied by Vibrating Sample Magnetometer (VSM). Pure Fe3O4 and Fe3O4@SiO2@TiO2 composites magnetization saturation (Ms) obtained 80 and 37 emu/g, respectively. also the remanent magnetization (Mr) value of Fe3O4 and Fe3O4 / SiO2 / TiO2 microstructures was 8 and 6. 43 emu/g, respectively.
