Synthesis and characterization of vanadium oxides nanorods

Vanadium oxides nanorods with high crystallinity and high surface area were synthesized by hydrothermal method using laurylamine hydrochloride, metal alkoxide and acetylacetone. The samples characterized by XRD, nitrogen adsorption isotherm, SEM, TEM, and SAED. Uniformly sized B phase VO2 nanorods had widths about 40-80 nm and lengths reaching up to 1 mu m. V2O5 rodlike structured with the widths about 100-500 nm and the lengths of 1-10 mu m were obtained by calcination at 400 degrees C for 4 h. This synthesis method provides a new simple route to fabricate one-dimensional nanostructured metal oxides under mild conditions. (c) 2005 Elsevier Inc. All rights reserved.
