| 摘 要： | 以溶胶－凝胶法，采用旋转涂膜工艺在玻璃表面制备了Ce,La掺杂的多孔TiO2薄膜，研究了玻璃表面TiO2薄膜在稀土掺杂及多孔化处理后的特征，发现稀土元素的掺杂使薄膜的多孔结构更加均匀一致，在近紫外的吸收率明显提高，同时对油酸有更高的光催化降解效率。

| Abstract: | Ce or La doped porous TiO_2 films coated on glass surface were prepared by sol-gel method using spinning technique.The influence of doping and porous surface structure on the photocatalytic degeneration efficiency of TiO_2 films for oleic acid was investigated by high pressure liquid chromatography and visible-ultraviolet spectropho- tometer.Atomic force microscopy was used to observe the morphology of porous surface.As a result,the cerium- doped TiO_2 film had the most uniform porous structure and the highest absorptivity,which led to higher photocatalytic degeneration efficiency for oleic acid. |
