本文对合成TiO2一维纳米材料及其有序纳米阵列的阳极氧化法、模板法以及水热法进行了全面而系统的评述,着重介绍了它们的最新研究进展。阳极氧化法能制备牢固负载于基体上的TiO2纳米管阵列,这有助于构筑TiO2纳米结构及其在纳米器件上的应用;与多种制备技术如溶胶-凝胶工艺、电化学沉积以及原子层沉积等相结合,模板法可以合成出多种形貌的TiO2纳米材料如纳米管、纳米线和纳米棒,并且可以通过改变所用模板的微观尺寸来调控TiO2一维纳米材料及其有序阵列的微结构参数;水热合成法可以制备出直径小且比表面积大的TiO2纳米管粉末。从目前来看,该法还不能制备出牢固负载于基体上的有序纳米阵列。文章最后指出了TiO2一维纳米材料及其有序纳米阵列合成中存在的问题及今后发展方向。
In this paper, the anodic oxidation, template method and hydrothermal method of one-dimensional nano-TiO2 nanomaterials and their ordered nano-arrays have been comprehensively and systematically reviewed, and their latest research progress is emphatically introduced. The anodization method can prepare TiO2 nanotube arrays which are solidly supported on the substrate, which helps to build TiO2 nanostructures and their applications in nanodevices. With an array of fabrication techniques such as sol-gel process, electrochemical deposition and atomic Layer deposition and so on. The template method can synthesize TiO2 nanomaterials with many morphologies, such as nanotubes, nanowires and nanorods, and can control TiO2 one-dimensional nanomaterials and their ordered arrays by changing the microscopic size of the template Of the microstructure parameters; hydrothermal synthesis method can be prepared with small diameter and large specific surface area of TiO2 nanotube powder. So far, the method can not prepare a well-ordered nano-array supported on the substrate. Finally, the paper points out the problems existing in the synthesis of TiO2 one-dimensional nanomaterials and their ordered nanoarrays and their future development.
