dc.descriptionComposite membranes for carbon dioxide separation were obtained with vacuum infiltration of an eutectic mixture of potassium and lithium molten carbonates into a samaria-doped ceria (SDC) porous matrix at high temperature. Porous SDC were obtained by thermal removal of LiF sacrificial pore former. Scanning electron microscopy and scanning probe microscopy micrographs allowed for estimating pore volume and molten carbonate percolation through porous SDC. Impedance spectroscopy measurements at temperatures below and above the melting temperature of the carbonates show the contributions of oxide and carbonate ions to the total electrical conductivity of the ceramic membranes, which is dependent on the pore volume.
