摘要
新型纳米材料TiO2纳米管阵列具有独特的、高度有序的阵列结构和良好的力学性能、化学稳定性以及抗腐蚀性能。该材料以纯金属钛为基体,在含有少量氟离子的电解质溶液中通过电化学阳极氧化法制得。本文综述了近年来TiO2纳米管阵列在不同电解液体系中的制备工艺、形成机理、修饰改性及其在光催化降解污染物、太阳能电池、气敏传感材料、光解水制氢等领域应用的最新研究成果,并指出目前存在的问题,对今后的研究提出了展望。
Titania nanotube arrays as a novel nano-material has unique highly ordered array structure, good mechanical and chemical stability, as well as excellent corrosion resistance. It has been fabricated by electrochemical anodization of pure Ti sheet in electrolytes containing small amounts of fluoric ions. This paper reviews the new research achievements of TiO2 nanotube arrays on the preparation processes, forming mechanism, modification and the applications in the photocatalytic degradation of pollutants, solar ceils, gas sensor materials, photolysis water. The existing problems and further prospects in this field are also discussed.
