| 摘 要： | 在AOT／异辛烷反胶束体系中制备了粒径为2－5nm的单分散球形TiO2纳米粒子，用TEM，DSC和XRD等手段对其进行了分析；用浸渍法以小孔分子筛HZSM－5为载体制备了负载型TiO2纳米粒子，用FTIR，Langmuir及BET等手段进行了表征；用以上2种TiO2粒子作光催化课时了简单模拟废水处理研究，用UV－Vis光谱分析其催化效果表明，负载型TiO2纳米粒子比纯TiO2纳米粒子的光催化活性更高。 |
| 关 键 词： | 反胶束体系 制备 负载型TiO2 纳米光催化剂 废水处理 二氧化钛 光催化活性 |

| Abstract: | TiO 2 nanoparticles with a diameter of 2-5 nm were prepared by reverse micelle method and characterized by TEM, DSC and XRD. The loaded nanosize TiO 2 photocatalyst supported by small porous molecular sieve HZSM 5 was obtained by impregnating method and identified by FTIR, Langmuir, BET and BJH adsorption. The synthesized pure TiO 2 nanoparticles and loaded nanosize TiO 2 were respectively used as photocatalyst to degrade K 2Cr 2O 7 in aerated solution. The UV Vis spectra indicated that the photocatalytic activity of the loaded TiO 2 nanoparticles was higher than that of the pure. |
