本文采用水热法制备了钛酸盐纳米管,并用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和紫外-可见光谱(UV-VIS)对样品进行了分析。以罗丹明B溶液为目标降解物,考察了样品的光催化性能。结果表明纳米管管径在8～20纳米之间,管长从几百纳米到几微米,具有不同于锐钛矿的钛酸盐结构。在紫外光照射下,钛酸盐纳米管的光催化性能明显高于TiO2纳米粒子,光照100分钟后降解率达到87%。
In this paper, titanate nanotubes were prepared by hydrothermal method. The samples were analyzed by XRD, SEM, TEM and UV-VIS . Rhodamine B solution as the target degradation products, investigated the photocatalytic properties of the sample. The results show that the nanotubes have a diameter of 8-20 nanometers and a tube length of several hundred nanometers to several micrometers, which has a titanate structure different from anatase. Under UV irradiation, the photocatalytic activity of titanate nanotubes was significantly higher than that of TiO2 nanoparticles, and the degradation rate reached 87% after 100 min illumination.
