摘要

采用射频溅射技术对沉积在玻璃基板上的Ti薄膜进行电阳极处理,制备了在350℃~ 650℃退火的TiO2纳米管。利用扫描电子显微镜(SEM)对其形貌进行了分析,发现随着退火温度的升高,表面形貌发生了变化。利用x射线衍射(XRD)和拉曼光谱对其进行了结构分析。XRD分析表明,TiO2存在锐钛矿相,在550℃,2θ(28,9°)处锐钛矿峰最强。拉曼光谱显示TiO2只存在锐钛矿相,并且随着退火温度的升高,其结晶度得到了很好的改善。

Structural and Morphological Properties of TiO2 Nanotubes Fabricated via Electro-anodization Process
Electro-anodization of thin Ti film deposited on glass substrate by RF sputtering technique was employed to fabricate TiO2 Nanotubes (TNTs) annealed from 350°C to 650°C. The morphological analysis were done using Scanning Electron Microscopy (SEM), which showed the change in the surface morphology with increase in annealing temperature. The structural analysis was performed using X-ray Diffraction (XRD) and Raman spectroscopy. XRD revealed the presence of anatase phase TiO2 with most intense anatase peak found at 550°C, at 2θ of 28, 9° (101). Raman revealed the presence of only anatase phase of TiO2, and showed well-improved crystallinity of the TNTs upon increasing in annealing temperature.
