Resumo
Composite 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.
