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%。

Titanate nanotubes were prepared by hydrothermal method, and the samples were characterized by X-ray diffraction (XRD), scanning electron microscope SEM), transmission electron microscope (TEM), UV-VIS spectrum. The photocatalytic properties of the samples were investigated in a Rhodamine B aqua. The results show that the diameter of the nanotubes ranges from 8 nm to 20 nm and the length in the range from hundreds of nanometer to a few microns.The structure of the nanotube is titanate that is different from anatase phase. Titanate nanotubes have better photocatalytic activity than that of the nanoparticles. The degradation rate is 87% after 100 min light exposure.
