文摘

Highly ordered TiO₂ nanotube arrays were successfully prepared by the combination of the electrodeposition method and the anodic aluminum oxide (AAO) templating method. X-ray diffraction showed that the TiO₂ nanotube arrays were of anatase phase. Scanning electron microscopy indicated that the wall thickness of the nanotubes was 20 nm and the external diameter of the TiO₂ nanotubes was about 100 nm, which is in good agreement with the pore diameter of the AAO template. Transmission electron microscopy indicated that the TiO₂ nanotubes were straight and had uniform thickness along the length. Finally, a possible growth mechanism of the TiO₂ nanotube arrays is also discussed.
