Abstract: |
Ba0.75Cd0.25SrTiFe10O19 hollow nanospheres were successfully prepared via a simple solvothermal method and were completely characterized. The size, morphology, and structure of the as-prepared 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. On the basis of the obtained experimental results, the possible formation mechanism was discussed. 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 and hollow porous material, SrBa0.75Cd0.25TiFe10O19 hollow spheres showed favorable degration behavior for Congo red. Factors affecting decomposition, such as, initial dye concentration, pH and contact time were evaluated. The combination of the photodegration and the magnetic properties of Ba0.75Cd0.25SrTiFe10O19 hollow nanospheres can be useful to destroy organic contaminants in wastewaters. |
