Abstract

Titanate nanotubes were synthesized by hydrothermal method using various TiO ₂ precursors as starting materials. The electrochemical properties were investigated by cyclic voltammetric methods. The microstructure and morphology of the synthesized powders were characterized by XRD, TEM. Titanate nanotubes composed of H ₂Ti ₂O ₅H ₂O with outer and inner diameter of ∼10 nm and 6 nm, and the interlayer spacing was about 0.65-0.74 nm. Also,-the titanate nanotubes showed a discharge capacity of 303 mAh/g and the highest cycle stability because of the open-end and rolled layers with suitable spacing. The relationships between morphology and electrochemical properties have been also discussed.
