Abstract

Titanium oxide nanotube (TNT), which can be synthesized by simple and low temperature solution chemical route without using any template, has unique open-end nano-scaled tubular structure. Because of the combination of low-dimensional nano-structure and physicochemical properties of TiO2, excellent multifunctionalities are expected and reported. In this paper, its potential as a energy creating and storage material has been investigated. TNT electrode was prepared to confirm the performance as an anode material for Li-ion battery. It was found that the TNT electrode acted sufficiently as the anode during charge discharge cycles. The capacity of TNT electrode at the 1st discharge cycle was found to correspond to theoretical value of TiO2. Degradation of capacity during the cyclic test was around 20%. These results imply that the TNT has certain potential as the anode material. On the other hand, it was also confirmed that the TNT has advantage as the electrode of sensitized solar cell. Detailed properties as the energy creating and storage materials in relation to its unique 1-D nanostructures will be discussed
