Experimental Study on Photocatalytic Mercury Removal by Titanium Dioxide

Abstract:

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.
