Magnetic Fe₃O₄@TiO₂ core-shell microspheres are ideally applied in several specific fields due to their unique properties. A facile liquid phase deposition route for the fabrication of Fe₃O₄@TiO₂ core-shell microspheres was developed. The core-shell structure was obtained by direct deposition of TiO₂ on the surface of Fe₃O₄ microspheres. The prepared products were characterized by using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). The waxberry-like microspheres were nearly spherical with diameters of about 500 nm and average shell thickness of 80 nm. The shell layer was composed of smaller primary TiO₂ nanoparticles with sizes from 10 to 20 nm. A possible growth mechanism of the core-shell structure was proposed. The photo-catalytic decomposition of methylene blue and the recycling of …
