摘要
采用钛酸四丁酯为主要原料,以溶胶-凝胶法制备TiO2及不同Ag含量的Ag-TiO2,通过X射线衍射仪及傅里叶红外光谱仪对其结构进行必要的表征。以高压汞灯为光源,研究了TiO2及Ag-TiO2对甲基橙的光催化降解情况。结果表明,掺杂Ag+的TiO2对甲基橙的光催化降解效果较好。
In this paper four butyl titanate is main raw material, prepared TiO2 and different Ag contents of the Ag-TiO2 by sol-gel method. By using X ray diffraction and Fu Liye infrared spectrometer its structure was characterized. Using a high pressure mercury lamp as light source, the initial concentration of methyl orange was degradated. The result indicated that the Ag ＋ doped TiO2 for methyl orange photocatalytic deg- radation effect is better than TiO2.
