Title:
CATALYST AND PRODUCTION METHOD FOR SAME, CATHODE, ION EXCHANGE MEMBRANE ELECTRODE ASSEMBLY, AND SOLID ELECTROLYTE ELECTROLYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/163052
Kind Code:
A1
Abstract:
Provided are a catalyst that has high electrolytic activity and a rapid CO2 reduction reaction rate, and a production method therefor. Also provided are a cathode, an ion exchange membrane electrode assembly, and a solid electrolyte electrolysis device. The catalyst has: a metal ion selected from the group consisting of a copper ion, a nickel ion, an iron ion, a cobalt ion, a zinc ion, a manganese ion, a molybdenum ion, and an aluminum ion; a nitrogen-containing compound; and a carrier comprising carbon and having a primary particle size of 5-200 nm. The metal ion is coordinated with a nitrogen atom on the nitrogen-containing compound, and the quantity of the metal ion that is coordinated with the nitrogen atom is at least 0.7 mass%. The catalyst has a particle size of 10 nm to 50 µm.
