Claims15
A method for preparing vanadium oxide nanoparticles comprising the inverse micelle hydrolysis of (1) a compound having the formula:
- OV(OR)3, V(OR)3, OV(OR)2 or mixtures thereof
- wherein:
- R is H or an organic group capable of forming ROH during the inverse micelle reaction, or
- (2) the reaction product or premix of (1) with an acid, wherein the conditions of the reaction are such that the hydrolysis and condensation rates of the compound are minimized sufficiently to at least inhibit premature precipitation and excess reduction of the VO2 particles produced by the reaction.
A method for preparing vanadium oxide nanoparticles comprising reacting a vanadyl ester having the formula VO(OR)3, wherein R is an alkyl group with a carboxylic acid in an aqueous medium, followed by precipitation therefrom of nanosize VO2 particles
Vanadium oxide nanoparticles.
The nanoparticles wherein said vanadium oxide is VO2.
