摘　　要：TiO2纳米管阵列作为一种新型的纳米TiO2材料,由于具有独特的阵列结构和优异的性能,引起了人们的极大关注。本文介绍了采用阳极氧化法制备TiO2纳米管阵列的工艺条件、产物特性、形成机理,及其在氢传感器、光解水制氢、染料敏化太阳能电池与光催化降解污染物等领域的应用,分析了目前存在的问题,并提出了今后研究的对策。Titania nanotube arrays, a new type of titania nanomateriais, have drawn extraordinary attention in recent years due to their distinctive morphology and notable performance. This paper introduces the preparation methods, properties, and forming mechanism of titania nanotube arrays fabricated by anodic oxidation. The applications of asprepared titania nanotube arrays in hydrogen gas sensors, photolysis of water, dye-sensitized solar cell, photocatalytic degradation of organic pollutants are reviewed. Problems in preparation and applications of titania nanotube arrays are suggested for further research.
