Abstract: Titanate nanotubes were prepared by hydrothermal method, and the products were characterized with TEM, XRD, and XPS. The diameter of the nanotube was around 5 nm to 30 nm with a length ranging from approximately 0.1 μm to 1 μm. The structure of the nanotube was that of titanate different from anatase phase; the composition of the products may be Na4-xHxTi2O5. The photoelectrochemical properties of the titanate nanotubes were investigated. Titanate nanotubes produced anodic photocurrent, exhibiting the property of the n-type semiconductor.
