Synthesis of nanosized V2O5 by the gel combustion method.

Abstract

Vanadium pentoxide powder has been synthesised at low temperature (550^oC) by the combustion of gel prepared from polyvinyl alcohol (PVA) and vanadium chlorid. The characterization of V205 powder is examined by X-ray diffraction (XRD), scanning electron microscopy (SEM) and BET (Brunaure-Emmet-Teller) measurements. Further thermal treatment at 400 - 60CPC in 1.5h yields the single phase V205 with average size < 50 nm. Its specific surface area is 23.50 m2/g for V205.
