Hydrothermal synthesis of vanadium oxide nanotubes from V2O5 gels

Vanadium oxide nanotubes (VOx-NT) have been synthesized in high yield by adding hexadecylamine to V2O5.nH(2)O gels, followed by a hydrothermal treatment (150-180degreesC, 2-7 days). Scanning electron microscopy (SEM) and X-ray diffraction analysis have been performed to optimize the temperature and reaction time required for formation of VOx-NT and the morphology of the nanotubes investigated by transmission electron microscopy (TEM).
