- Abstract
Stibium doped titanium dioxide nanocomposite was prepared with stibium( ) chloride, titanium sulfate as raw materials and Sodium dodecyl sulfate as surfactant under microwave irradiation. Then the X-ray diffractometer (XRD) and the scanning electron microscopy (SEM) were used to observe the antimony-doped TiO2 nanocrystalline composite. The results show that the as-prepared nanocomposite of inventory molar ratio of 2% calcined at 500 for 2 h is anatase, the morphology is irregular sheet structure composed of many particles. We studied the photocatalytic activity of the as-prepared samples by using degradation of methyl orange. The result indicates that the as-prepared Sb3+-doped TiO2 nanocomposite is a good photocatalyst. The effects of photocatalytic activity of the composite with different ratios of qualities of inventory molar ratio,calcined at different temperature, different amount of hydrogen peroxide, different amount of nanocomposite, and the acidity of the solution were investigated. Also, different concentration of methyl orange as model affects it. When the catalyst was 1.0 g/L, pH value was 2.5, C(H2O2) was 3 mL/L, the degradation rate of sample for methyl orange of 20 mg/L reached 99.27% in 40 min.
