Characterization and Application of Mesoporous Titanium Dioxide Prepared by Normal Temperature Hydrolysis |
| |
| Abstract: | Using n-cetylpyridinium chloride as template, mesoporous TiO_2 was prepared by direct synthesis at room temperature. At the same time,the effect of synthesized conditions on samples were studied. The samples were characterized by FT-IR, TG-DTA, XRD, and N_2 adsorption techniques respectively. The results show that specific surface and thermal stabability are improved by using mesitylene and phosphoric acid. At the same time, it can exhibit the better photoreactivity. |
