    摘要
  • 摘要: 以鈦酸四丁酯為前驅體,采用溶膠-凝膠法在玻璃板表面制得均勻的TiO2,并利用浸漬法鍍Pb2+得到摻鉛的TiO2,用紫外漫反射、熒光光譜分析等手段對其進行了表征.研究結果表明,摻雜鉛離子使TiO2的熒光峰明顯增強,吸收帶邊發生紅移,在紫外光區和可見光區的吸收明顯增強.以紫外燈為光源,通過對甲基橙的光催化降解研究,發現摻鉛TiO2薄膜的光催化活性明顯大于摻Ag,Bi及純TiO2薄膜,這是提高TiO2光催化活性的有效方法.

     

    Abstract: A TiO2 catalyst doped by Pb2+ was prepared by the sol-gel method and characterized by DRS and FS. The experimental results showed that Pb2+ strengthened the TiO2 fluorescence apex, the absorbance band edge moved in the red direction, and the absorbance strengthened obviously both in the UV range and in the visible range. Compared with Ag-TiO2, Bi-TiO2 and TiO2 films, the Pb2+-doped TiO2 thin film has the highest photocatalytic activity by studying the degradation of methyl orange under UV-ray, which is an effective way to increase the photocatalytic activity.
