摘要: Titania (TiO2)-based photocatalysts decorated with different amounts of indium oxide (In2O3) were prepared by a pore impregnating method and characterized the Brunauer–Emmett–Teller (BET) method, X-ray diffraction (XRD), UV–Vis diffuse reflectance spectroscopy (DRS), photoelectron (XPS). The separation efficiency photogenerated charges was investigated using benzoquinone (BQ) as scavenger. activities evaluated decolorization methyl orange (MO) aqueous solution under ultraviolet-light irradiation. Compared to TiO2, In2O3/TiO2 composites show improved photocatalytic performance due coupling effect TiO2 In2O3, which greatly improves electrons holes.
