The magnetic anatase titania (TiO2) hollow spheres have been fabricated as magnetic photocatalyst by template (polystyrene)-sacrificed method, in which cobalt ferrite and titania was sequentially deposited on the surface of polystyrene spheres via coprecipitation and sol-gel process followed by calcinations. X-ray diffraction (XRD), transmission electron microscopy (TEM), and vibrating sample magnetometer (VSM) were employed to characterize the products, and the photocatalytic activities were evaluated by photodegradation of methyl orange (MO) under UV illumination. The results indicate that the as-prepared magnetic titania hollow spheres exhibit magnetic property and high photocatalytic activity.
