Conductive membrane for carbon dioxide separation

摘要

Disclosed are a conductive membrane able to selectively separate carbon dioxide from a gas mixture containing carbon dioxide, a manufacturing method thereof, and a method of separating carbon dioxide using the membrane. The conductive membrane for carbon dioxide separation includes molten carbonate, acting as a carbonate-ion conductor, and oxide, acting as an electronic conductor, and has infinite selectivity for carbon dioxide at high temperatures of 500° C. or more.
