Abstract
The present invention relates to a method for synthesizing tungsten oxide nanoparticles and to the tungsten oxide nanoparticles obtainable on the basis of the claimed synthesis method.
Claims18
A method for synthesizing tungsten oxide nanoparticles, comprising the following consecutive steps:
- a) dissolving a halogenated tungsten compound in an alcohol having a standard boiling point of greater than or equal to 120° C., b) controlling the temperature to a value of between 60° C. and the standard boiling point of the alcohol less 5° C., c) adding oxalic acid, d) controlling the temperature to a value of between 80° C. and the standard boiling point of the alcohol less 5° C., at least greater than the temperatures of step b), and e) obtaining tungsten oxide nanoparticles comprising oxalic acid ligands.
