CATALYST, CATHODE, ION EXCHANGE MEMBRANE-ELECTRODE ASSEMBLY AND SOLID ELECTROLYTE ELECTROLYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/163042
Kind Code:
A1
Abstract:
The present invention provides: a catalyst which has a high production efficiency of a synthesis gas containing CO; a cathode; an ion exchange membrane-electrode assembly; and a solid electrolyte electrolysis apparatus. This catalyst comprises: fine particles of a substance that is selected from the group consisting of gold, silver, copper, nickel, iron, cobalt, zinc, chromium, palladium, tin, manganese, aluminum, indium, bismuth, molybdenum and carbon nitride; or a metal selected from the group consisting of copper, nickel, iron, cobalt, zinc, manganese, molybdenum and aluminum, or a metal complex wherein a ligand is coordinated to an ion of any one of these metals; and a carrier that contains carbon. The carrier has a nitrogen-containing heteroaryl group having a primary amino group on the surface.
