Ag修饰TiO2的制备及其在模拟太阳光下的光催化性能研究
Preparation and Photocatalytic Activity of Ag-modified TiO2 under Simulated Solar Light
摘要
Abstract
Ag-modified and pure TiO2 were prepared via sol-gel method and characterized by XRD, EDS, XPS, SEM, UV-Vis and PL systematically.The results show that the crystal structure of pure TiO2 is anatase/rutile mix phase and all the Ag-TiO2 form anatase phase, in which Ag is metallic Ag0.The crystallite size was refined and the transition from anatase to rutile was inhibited by Ag adding.The RhB solution was used as target pollutant and the photocatalytic activity of prepared samples under simulated solar light was investigated.The experimental results show that the photocatalytic activity of TiO2 was enhanced evidently via Ag adding and 4%Ag-TiO2 exhibits best photocatalytic activity.The degradation of 4%Ag-TiO2after 3 h is 83.3%, which is 1.68 times higher than that of pure TiO2.The reaction rate constant k of 4%Ag-TiO2 is 0.00896 min-1, which is 3.12 times higher than that of pure TiO2.关键词
