Vanadium oxide nanostructures were successfully synthesized by hydrothermal
process using V2O5 as a starting source material. The process was conducted at 120
ºC for 48 h using different reductants including n-butanol and acetylacetone. The
essential physical properties of as-synthesized products were characterized by XRD,
Raman spectroscopy, SEM and TEM. The XRD and Raman results revealed that the
crystalline structure and phase of the samples are highly dependent on the reductant
types. The SEM images enclose that as-prepared samples possess different
morphologies depending on different reactant. The phase transformation from V2O5
to VO2 can be also carried out by this process with assistance of these reactants.
