Title:
CATALYST AND ELECTROCHEMICAL CELL COMPRISING CATALYST
Document Type and Number:
WIPO Patent Application WO/2019/098474
Kind Code:
A1
Abstract:
The present invention relates to: an electrochemical cell to be used when carbon dioxide is decomposed and reduced to a useful conversion product; and a catalyst to be used in an electrode for an anode within the cell. According to the present invention, a compound having the carbon number of 2 or more can be selectively generated and a hydrocarbon having the carbon number of 2 or more can be stably generated by providing, as a catalyst for a reduction reaction of a material, a catalyst comprising a metal compound containing a metal ion having a standard reduction potential lower than the standard reduction potential when a monovalent or divalent copper cation within copper oxide is reduced to copper or a monovalent copper cation, and thus a catalyst having durability can be provided.
