摘　　要：二氧化钛因其在光催化、染料敏化太阳电池、生物医药等应用领域表现出优异性能而成为材料科学领域重点研究的化合物之一。本文介绍了近年来阳极氧化法制备不同形貌的TiO2纳米管(TiO2NTs)阵列,探讨了电解液、阳极氧化时间、电压三个因素对TiO2纳米管形貌的影响,综述了掺杂、复合、表面修饰这三种能对TiO2纳米管进行化学或物理修饰的改性手段以及改性后的TiO2纳米管阵列在光催化、太阳能电池、生物医学、传感等领域的应用研究进展。最后,指出国内外针对二氧化钛纳米管阵列研究现状所存在的问题,并对今后的研究工作提出了展望。TiO2 is one of the most studied compounds in materials science because of some outstanding properties it is used for instance in the field of photocatalysis, dye-sensitized solar ceils, and biomedicine. In this review, TiO2 nanotubes （TiO2NTs） arrays of different morphologies prepared by electrochemical anodization methods in recent years were introduced and different electrolyte,anodization time and voltage, which have an effect on the morphologies of TiO2 nanotubes, were investigated. The physical or chemical modification methods of TiO： nanotubes, including doping, composite, surface decoration were described in detail. Varies of applications of modified TiO2 nanotubes arrays, such as photocatalysis, solar cells, biomedicine and sensors were summarized. Finally, the existing problems and further prospects in this research field were discussed.
