Bundled tungsten oxide nanowires with controllable morphology were synthesized by a simple solvothermal method with tungsten hexachloride (WCl{sub 6}) as precursor and cyclohexanol as solvent. The as-synthesized products were systematically characterized by using scanning electron microscopy, X-ray diffraction and transition electron microscopy. Brunauer-Emmett-Teller gas-sorption measurements were also employed. Accompanied by an apparent drop of specific surface area from 151 m{sup 2} g{sup -1} for the longer nanowires synthesized using a lower concentration of WCl{sub 6} to 106 m{sup 2} g{sup -1} for the shorter nanowires synthesized using a higher concentration of WCl{sub 6}, a dramatically morphological evolution was also observed. With increasing concentration of tungsten hexachloride (WCl{sub 6}) in cyclohexanol, the nanostructured bundles became larger, shorter and straighter, and finally a block-shape product occurred.
