product were investigated in details by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Magnetic hysteresis measurement carried out on vibrant sample magnetometer (VSM) shows strong ferromagnetic property at room temperature. These magnetic spheres, which could be easily recovered by a magnet, exhibited high efficiency in the photocatalytic decomposition of dye contaminants from water. Because of the high specific surface area, nano-scale particle size andhollow porous material, BaoisCd5SrTiFe10019 hollow spheres showed favorable degradationbehavior for Congo red. Factors affecting decomposition, such as, initial dye concentration, pH andcontact time were evaluated.
