In the past decade, different methods for synthesizing titania nanotubes have arisen, and several models have been proposed to explain the mechanism, such as the roll-up formation model and the oriented crystal growth model. But there are some disputes between the models and, on the basis of the results of our experiments, we think that the mechanisms for forming titania nanotube have some shortcomings. In this paper, a novel method for synthesizing titania nanotubes by microwave irradiation is briefly introduced. On the basis of transmission electron microscopy (TEM) and high-resolution (HRTEM), we suggest that a novel formation mechanism, titania nanotubes formed from tiles overlapping from the initial tubules, can explain the results of the experiments.

微波辐射合成TiO2纳米管的瓦片重叠模型

在过去的十年中，出现了不同的合成二氧化钛纳米管的方法，并提出了几种模型来解释其机理，例如卷起形成模型和定向晶体生长模型。但是模型之间存在一些争议，根据我们的实验结果，我们认为形成二氧化钛纳米管的机制存在一些缺陷。本文简要介绍了一种利用微波辐射合成二氧化钛纳米管的新方法。在透射电子显微镜 (TEM) 和高分辨率 (HRTEM) 的基础上，我们建议一种新的形成机制，即由初始小管重叠的瓷砖形成的二氧化钛纳米管，可以解释实验结果。
