摘要：
Based on anodic aluminum oxide (AAO) templates prepared in different acidic solutions, highly ordered aligned titania nanotubes array films have been successfully prepared by the liquid phase deposition method. The effect of AAO template type on the microstructure of titania film have been studied. Using the template with a certain volume fraction of Al2O3 (less than 0.71), ordered aligned titania nanotubes were obtained, characterized with an outer diameter of 200 nm and an inner diameter of 100 nm, respectively. However, titania existed as ordered aligned nanorods with the diameter of 100 nm when the template with large volume fraction of Al2O3 (larger than 0.71) was used. TiO2 thin films calcined at 400°C for 4 h have an anatase phase and exhibit good photocatalytic activity, i.e., 75% methylene blue could be degraded under ultraviolet irradiation for 2 h.
