　　用阳极氧化法制备出高度致密、有序的TiO2纳米管阵列。利用SEM和XRD表征分析纳米管阵列的形貌和结构，并通过电化学瞬时光电流对TiO2纳米管阵列的光电化学特性进行了研究。实验结果表明：经过500℃退火后的TiO2为掺杂有金红石相的锐钛矿的混晶结构。随着退火温度升高到600℃，金红石型的晶相比例增加。光电测试结果表明：随着退火温度升高，瞬时光电流减小，同时阳极氧化时间影响TiO2纳米管阵列光电极的光电性能。

TiO2 nanotube arrays were fabricated by anodic oxidation on a titanium sheet. The morphology and structure of the nanotube arrays were characterized by SEM and XRD. The photoelectric properties of the nanotube arrays electrodes were evaluated by transient photocurrents. The results show that the structure of nanotube arrays is a mixture phase of anatase and rutile annealed at 500℃. With the annealing temperature increasing to 600℃, the phase ratio of rutile increases. Photoelectric test results show that: the instantaneous photoelectric current decreases as the annealing temperature increases and at the same time, anodic oxidation time affects the photoelectric properties of nanotube arrays photoelectrode.
