摘要

The photocatalytic degradation of Rhodamine B dye was successfully carried out under UV irradiation over porous TiO_2-SnO_2 nanocomposites with various molar ratios of Ti/Sn (4-12) synthesized by hydrothermal method using polystyrene microspheres as template. The combination of TiO_2 with SnO_2 can obtain high quantum yield of TiO_2, and then achieve the high photocatalytic activity. And its porous structure can provide large surface area, leading to more adsorption and fast transfer of dye pollutant. Structural and textural features of the samples were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), and N_2 sorption techniques. Both adsorption and UV irradiation contribute to decolorization of about 100% of Rhodamine B dye over the sample TiSn10 after 30 min of the photocatalytic reaction, while the decomposition of Rhodamine B dye is only 62% over pure titania (Degussa P25).
