TEM Study on the Formation Process of TiO₂ Nanotubes

Lab of Special Functional Materials, Henan University, Kaifeng 475001

Received Date: 29 October 2002

Fund Project: This project was supported by the National Natural Science Foundation of China (20071010).

The process, that the polycrystalline TiO₂ powders were converted into TiO₂ nanotubes, was observed with transmission electron microscope. The results obtained indicated that in concentrated NaOH aqueous solution, anisotropic swelling appears on the polycrystalline TiO₂ granula at first, and then the nanotubes are formed.
