Vanadium oxide nanotubes were synthesized using V2O5 powder as the precursor and
hexadecylamine as the structure-directing template using a sol-gel reaction method followed by a
one-step hydrothermal treatment. The structure and morphology of the nanotubes were investigated
by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The inner
and outer diameters of the nano tubes varied from 30 to 40 nm and 50 to 130 nm, respectively. The
nano tubes measured several micrometers in length.
