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.
