一种Ti纳米管、其制备方法和用途

本发明涉及一种Ti纳米管、其制备方法和用途。所述Ti纳米管的制备方法包括如下步骤：(1)在碳纳米棒表面沉积金属Ti，得到镀Ti碳纳米棒；(2)除去所述镀Ti碳纳米棒中的碳纳米棒，得到Ti纳米管。本发明的制备方法可以很好的控制沉积金属Ti的厚度，得到的Ti纳米管均匀性较好；同时，相比于现有技术采用化学气相沉积法制备的Ti纳米管长度上限在5～10μm间，本发的方法得到的Ti纳米管长度可控，与碳纳米棒的长度相同，在保证管状结构的情况下，远超于化学气相沉积法制备的Ti纳米管长度。本发明制备方法简单，可工业化生产，具有优异的实用化前景。

The invention relates to a Ti nanotube as well as a preparation method and application thereof. The preparation method of the Ti nanotube comprises the following steps: (1) depositing metal Ti on thesurface of a carbon nanorod to obtain a Ti-plated carbon nanorod; and (2) removing the carbon nanorod in the Ti-plated carbon nanorod to obtain the Ti nanotube. According to the preparation method disclosed by the invention, the thickness of deposited metal Ti can be well controlled, and the obtained Ti nanotube is relatively good in uniformity. Meanwhile, compared with the prior art that the upper limit of the length of the Ti nanotube prepared by adopting a chemical vapor deposition method is 5-10 microns, the length of the Ti nanotube obtained by the method is controllable and is the same as the length of the carbon nanorod, and the length of the Ti nanotube is far greater than that of the Ti nanotube prepared by adopting the chemical vapor deposition method under the condition that a tubular structure is guaranteed. The preparation method is simple, can be used for industrial production and has an excellent practical prospect.
