二氧化钛纳米管由于其特殊的结构和优异的性能,在很多领域都有着重要的应用前景。阳极氧化法是制备二氧化钛纳米管的一种主要方法。近来,在阳极氧化法中使用有机电解液来制备二氧化钛纳米管取得了非常显著的效果。与传统的水溶性电解液相比,其深宽比和光电转换效率有了很大的提高。本文主要介绍了二氧化钛纳米管的阳极氧化原理以及有机电解液在阳极氧化法中对二氧化钛纳米管生长过程的影响。

Titania nanotubes have special structures and excellent performances, which draw a great many researchers’ attention. Anodic oxidization is one of the most important methods to fabricate titania nanotubes. Recently, some researches have made remarkable achievements by using organic electrolytes in anodic oxidization. Compared with conventional aqueous HF-based electrolytes, the titania nanotubes prepared from nonaqueous organic electrolytes exhibit higher aspect ratio and higher photoconversion efficiency. This paper reviews the principle of titania nanotubes fabrication and the influence of the organic electrolytes on the growth of titania nanotubes in anodic oxidization.

Contents
1 The mechanism of anodic oxidization
2 Organic electrolyte
2.1 The influence of organic electrolyte on TiO2 nanotubes
2.2 The photoelectric characteristics of TiO2 nanotubes fabricated in organic electrolyte
3 Suggestions and prospects
