TiO2 nanobelts from commercial TiO2 annatase phase were successfully synthesized via an alkali- hydrothermal process. The nanobelts are characterized by Thermogravimetric-Differential Thermal Analysis TG-DTA, X-ray Diffraction XRD, Infrared Spectra IR, and Scanning Electron Microscope SEM. The characterization indicates that the nanobelts with typical widths of 50 to 200 nm, thicknesses of 20 to 50 nm, were up to one hundred micrometer in length. The formation and transition mechanism of TiO2 nanobelts can also be discussed in this paper.
