| Abstract: | TiO 2 nanotubes were prepared with a simple chemical method. The titania nanotubes with high specific surface area and pore volume were studied by TEM and XRD. The specific surface area and pore volume of the TiO 2 nanotubes were affected by treating temperature. The results indicat that TiO 2 nanotubes prepared by this method are of smaller diameters, and that their shape is more uniform than those prepared by template method. The specific surface area of the nanotubes>200m 2/g, and the largest pore volume can reach 0.784cm 3/g. |
