Abstract

Abstract: Ag-TiO₂ catalyst was prepared by the sol-gel method. The nanoparticles were characterized by means of X-ray diffraction (XRD),scanning electron microscopy (SEM),N₂ adsorption-desorption isotherm (BET),and transmission electron microscopy (TEM). Degradation of methylene blue (MB) was studied at different doping contents and different calcination temperatures. The results showed that the specific surface areas of the samples increased and the transition from anatase to rutile were greatly inhibited when the calcinated temperatures was 800℃。 Also the photocatalytic activity was found to increase after Ag was doped. When the calcinated temperature was 500℃ and 1% Ag doped TiO₂ nanoparticles were irradiated under ultraviolet light,the degradation rate of MB reached 90% after 180min.

摘要： 采用溶胶-凝胶法制备了Ag/TiO₂光催化剂。通过X射线衍射(XRD)、场发射扫描电子显微镜(FE-SEM)、N₂吸附-脱附(BET)、透射电子显微镜(TEM)对产物进行了表征。以亚甲基蓝(MB)为降解物,考察了不同Ag含量和不同煅烧温度对样品的光催化性能影响。结果表明,掺杂Ag后,增大了样品的比表面积,800℃时,Ag的引入抑制了TiO₂锐钛矿向金红石相的转变,掺杂后TiO₂的光催化活性大大提高,在500℃煅烧温度下,当Ag的摩尔分数为1%时,在紫外光照射下,经过180min光催化实验,对MB的降解率达到90%.
