Hydrothermal Synthesis of Vanadium Oxide Nanorods by Surfactant-Assisted Method

Abstract

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 VO2 nanorods had widths about 40-80 nm and lengths reaching up to 1 μm. V2O5 rodlike structured with the widths about 100-500 nm and the length of 1-10 μm were obtained by calcination at 400 oC for 4 h. This synthesis method provides a new simple route to fabricate 1-D nanostructured metal oxides under mild conditions.
