  • IRIDIUM-MANGANESE OXIDE COMPOSITE MATERIAL, IRIDIUM-MANGANESE OXIDE COMPOSITE ELECTRODE MATERIAL AND METHODS FOR PRODUCING THE SAME
    Publication number: 20240279829
    Abstract: Provided are an iridium-manganese oxide composite material and an iridium-manganese oxide composite electrode material that are inexpensive and have high catalytic activity for use in an anode catalyst for oxygen evolution associated with water electrolysis. Also provided are methods for producing the same. An iridium-manganese oxide composite material includes a manganese oxide and iridium distributed on at least a surface of the manganese oxide, the iridium having a metal valence of 3.1 or greater and 3.8 or less. An iridium-manganese oxide composite electrode material includes a conductive substrate formed of a fiber, with the iridium-manganese oxide composite material being coated on at least a portion of the conductive substrate.
