- Abstract
In this paper, Cu2+ and Fe3+co-doped titanium dioxide nanocomposite was prepared by iron nitrate, copper nitrate and titanium sulfate as raw materials and sodium dodecyl sulfate as surfactant under microwave irradiation. The x-ray diffraction (XRD) results show that as-prepared sample of direct adding doped copper and iron content were 1.0% and 0.5% of titanium sulfate amount of substance calcined at 500 for 2 h is anatase. The SEM graph shows the morphology of the as-prepared samples is sheet structure composed of many particles. We also studied the photocatalytic activity of the as-prepared Fe3+ and Cu2+ co-doped TiO2 nanocomposite by using degradation of methyl orange solution simulated organic wastewater. The effect conditions of photo-catalytic activities of the composite were investigated, such as different ratios of direct adding doped iron and copper content, different dosage of hydrogen peroxide, different pH value, and different dosage of nanocomposite. When the catalyst is 1.0 g/L, pH value is 4.3, C(H2O2) is 3 mL/L, the effect of the visible light catalytic activity was the best, in 30 min, the degradation rate of 20 mg/L methyl orange solution was more than 97%.
