Vertically oriented TiO2 nanotube arrays having lengths up to 100 microns were prepares by anodic oxidation in organic electrolytes. Control of surface morphology of TiO2 nanotube arrays were surveyed principally, in order to improve the photoelectrochemical property of TiO2 nanotube array from a point of view of microstructure modification; based on these results, the photoelectrochemical properties of the nanotube arrays electrodes with different operation condition were evaluated. The results show that the surface collective block section can be removed entirely by ultrasonic cleaning in ethyl alcohol and the followed rinsing with double distilled water. The clean, regular and highly ordered nanotube arrays surface are obtained with an optimal ultrasonic duration 20-30 s. The as-prepared nanotube-array samples by single step anodic oxidation plus ultrasonic cleaning in ethyl alcohol with another 500 oC annealing show a remarkable photoconversion efficiency of 1.48% under full-spectrum illumination. It is believed that the control of surface morphology may be profitable for the improvement of the photoelectrochemical properties of TiO2 nanotube array.
