ZHANG Yun huai; et al.(College of Chemical Engineering; Chongqing University; Chongqing; 400044; China) |
Abstract:The TiO 2 film photocatalysts immobilized on flyash microsphere were prepared by Sol Gel method.The crystal phase and morphology of TiO 2/microsphere were investigated by XRD,SEM,BET.The photocatalytic activities of TiO 2/microsphere with different prepared condition and the TiO 2 amount on microsphere was evaluated by degradation of phenol. |
Key words:titanium dioxide; fly ash microsphere; photocatalyst; phenol |
