Preparation and doping of anodic TiO ₂ nanotube array

The preparation and application of Ti0₂ nanotube array are widely investigated in recent years. Anodic oxidation adopted to prepare Ti0₂ nanotube array has attracted intensive attention due to its simplicity, low cost and easy industrialization. The preparation of Ti0 ₂ nanotube array by anodic oxidation is reviewed in this paper. Key factors affecting the formation of anodic Ti0₂ nanotube array are discussed based on the formation mechanism of anodic Ti0₂ nanotube array. In combination with the results of our research group, how to adjust tube diameter, tube length, wall thickness, and improve the quality of surface morphology of anodic Ti0₂ nanotube array by changing voltage, potential sweep rate, electrolyte, temperature and oxidation time are summarized. Finally, the development on the doping of anodic Ti0₂ nanotube array is presented.
