Process for the preparation of nanoparticles of the oxide of vanadium BRONZE SODIUM

摘要

1. A method of producing nanoparticles sodium vanadium oxide bronze, comprising preparing a reaction mixture containing meta-vanadate sodium hydrate, the addition of sodium hydroxide to the mixture, a room in an autoclave and the hydrothermal treatment of the reaction mixture at an elevated temperature, followed by filtration, washing and drying, wherein that the reaction mixture further comprises a vanadyl sulfate hydrate composition VOSO · 3HO, taken in an equimolar amount with respect to the hydrate of sodium metavanadate NaVO · 2HO.2. A method according to claim 1, characterized in that sodium hydroxide is added until a pH, equal to 7.5 ÷ 9.5.
