具有高可见光催化性能W掺杂纳米TiO2的制备与表征
Preparation and Characterization of W Doped TiO2 with High Visible Light Photocatalytic Activity
摘要
Abstract
Nano-sized W doped TiO2 photocatalysts were synthesized by a simple hydrothermal method. X ray diffraction, field emission scanning electron microscope, field emission transmission electron microscope, ultraviolet -visible light absorption spectrum and photoluminescence spectrum were used to characterize the photocatalysts. The photocatalytic activity was evaluated by photocatalytic oxidation degradation of rhodamine B dye in aqueous solution under ultraviolet light and visible light irradiation. The doped amounts of W were investigated. The results show that the optimum doped molar fraction of W is 40% , and the photocatalytic activity of the 40 % W doped TiO2 photocatalysts under visible light irradiation is much higher than that of the pure TiO2 nano-particles and commercial P25.关键词
