| 摘 要： | 采用溶胶－凝胶法，以钛酸丁酯为前驱体，以不同添加量的聚乙二醇（ＰＥＧ，分子量２０００）为添加剂． 在普通载玻片上制备结构可控的多孔ＴＩＯ２纳米薄膜。结果表明：通过调节ＰＥＧ添加量，可以有效地调控薄 膜的结构（如孔径和孔分布），增大比表面积，进而可提高光催化活性。

| Abstract: | TiO2 porous nanometer thin films with controlled structure desposited on slide glass substrates were prepared from TiO2 sol ln the presence of PEG by sol-gel method. The results showed that the addition of PEG could adjust the morphology of thin films, such as pore size and pore distribution. As a result, it has been found that the specific surface area was increased and the phutocatalytic activity was improved. |
