Abstract
A low-cost and easy-to-fabricate mixed eand COconducting membrane for advanced high-flux and selective electrochemical COseparation from flue gas is provided. The membrane includes a CO-conducting molten carbonate phase and an e-conducting lithiated Ni-oxide interphase that can be formed in situ during operation. The membrane exhibits a COflux density greater than 0.8 mL/(minute·cm) at 850° C. with a selectivity ranging from about 100 to about 500 and excellent stability for up to about 450 hours. Further, the self-formed interphase LiNiOis highly electron conducting and can provide electrons to the co-reduction of COand Ointo CO. Such a membrane is an alternative to the conventional 'size-sieving' inorganic and 'dissolution-diffusion' organic counterparts for COcapture from flue gas.
