摘要:

在水热条件下, 控制反应温度和氢氧化钠的浓度, 分别采用去离子水和盐酸进行洗涤处理, 在钛金属基底表面合成出含钠元素和不含钠元素的两种钛酸盐纳米管薄膜(TiNTW和TiNTA), 并利用X射线衍射分析、扫描电子显微镜、透射电子显微镜和能量色散X射线光谱等对其结构、组成和性质进行了表征. 结果表明, TiNTW和TiNTA均由宽约8 nm、长约1 μm的纳米管组成, 但TiNTA表现出较好的光催化活性和储氢性能, 而热稳定性弱于TiNTW, 二者在性质上的显著区别归因于2种钛酸盐纳米管薄膜的晶体结构和元素组成的不同.

Abstract:

Titanate nanotube films with or without sodium contents(TiNTW and TiNTA) were synthesized on a titanium metal flake by hydrothermal treatment and washed with H2O or HCl. The films were characterized by means of X-ray diffraction(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM) and energy dispersive X-ray(EDX) spectroscope. The as-prepared nanotube films, TiNTW and TiNTA, were about 8 nm in width and 1 μm in length. They had similar morphologies and different properties. Relatively, TiNTA showed better photocatalytic activity and hydrogen storage ability, TiNTW showed higher thermal stability. The different properties of the two films were attributed to different element constitute and crystalline structure.

Key words: Titanate, Nanotube, Thermal stability, Photocatalytic activity, Hydrogen storage
