Title:
CATHODE ELECTRODE, COMPOSITE OF CATHODE ELECTRODE AND SUBSTRATE, ELECTROLYTIC REDUCTION DEVICE COMPRISING CATHODE ELECTRODE, AND METHOD FOR PRODUCING COMPOSITE OF CATHODE ELECTRODE AND SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2024/024709
Kind Code:
A1
Abstract:
The present invention provides: a cathode electrode that makes it possible to maintain, stably and with high efficiency over a long period, a catalytic reaction that produces an alcohol such as ethanol or an olefin-based hydrocarbon such as ethylene via a reduction reaction of carbon dioxide; and a composite of a cathode electrode and a substrate. Provided is a cathode electrode that electrically reduces carbon dioxide, said cathode electrode comprising copper and at least one additional element selected from the group consisting of aluminum, boron, gallium, zinc, titanium, and silicon, wherein the copper includes zero-valent copper, monovalent copper, and/or divalent copper.
