Popis: TiO2 hollow sphere was synthesized by hydrothermal method using Trifluoroacetic acid (TFA) and Ti (SO4)2 as raw materials. The photocatalytic properties of TiO2 hollow sphere were evaluated by the photocatalytic oxidization of elemental mercury (Hg0) in simulated flue gas. The as-prepared samples were well characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible diffuse reflectance spectroscopy and nitrogen sorption/desorption. The results show that only anatase phase for TiO2 the hollow sphere is obtained. The average diameter is about 800nm and the shell thickness was about 200nm. The sample prepared with TFA has better photocatalytic properties than P25.
