| 摘 要： | 以天然沸石作载体,在溶胶一凝胶法制备TiO2时直接掺入金属单质w进行改性,并在真空条件下锻烧制备沸石负载w/TiO2薄膜.在紫外光照射下降解甲基橙溶液,改性后的TiO2一阶反应速率常数k比未改性TiO2高,其光催化活性得到改善.

| Abstract: | Titania film was prepared by the sol-gel method,which was basing on natural zeolite substrate.A titania film sample was doped with W metal ions during the preparing process,and the sample was calcined by a vacuum furnace later.Photo-degradation experiment was carried out under UV-light in the methyl orange solution,the result indicated the dynamics reaction constant k of W/TiO2 was higher than those of the pure titania films under UV light,namely,the photocatalytic ability of TiO2 films under UV-light was e... |
