Title:
IRIDIUM-CONTAINING OXIDE, METHOD FOR PRODUCING SAME AND CATALYST CONTAINING IRIDIUM-CONTAINING OXIDE
Document Type and Number:
WIPO Patent Application WO/2022/138309
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to obtain an iridium-containing oxide that achieves both high activity and high durability and that makes it possible to reduce the amount of catalyst used, when serving as a water splitting electrode catalyst in cation exchange membrane water electrolysis or a cation exchange membrane fuel cell, as a result of controlling the pore structure. An iridium-containing oxide according to the present disclosure is characterized by having a total pore volume of 0.20 cm3/g or greater, as calculated by the BJH method from a nitrogen adsorption/desorption isotherm measurement, and by having a pore distribution in which the average pore diameter is 7.0 nm or greater.
