Title:
METHOD FOR PREPARING IRIDIUM OXIDE
Document Type and Number:
WIPO Patent Application WO/2023/113411
Kind Code:
A1
Abstract:
Provided is a method for preparing iridium oxide, comprising the steps of: preparing iridium chloride; mixing iridium chloride, a solvent and a pore control agent so as to prepare a dispersion solution; mixing the dispersion solution with an ion exchanger and performing ion exchange; removing the solvent from the dispersion solution so as to prepare a powder; and heat-treating the powder.
