Combustion-assisted CO2 capture using MECC membranes

Fast electrochemical CO2 transport through a dense metal-carbonate membrane: A new mechanistic insight

“…Recently, we demonstrated a new mixed electron and carbonate-ion conducting (MECC) silver-carbonate duel-phase membrane for carbon capture [8][9][10][11]. Fig.…”

Stabilizing electrochemical carbon capture membrane with Al2O3 thin-film overcoating synthesized by chemical vapor deposition

“…We have demonstrated the concept in one of our early publications. 24 Therefore, O 2 is not considered non-selective to the CO 2 capture in this case. The relevant microstructural differences corresponding to the drastically different flux stability observed in Fig.…”

Concurrent and modulated separation of CO2 and O2 by a fluorite/perovskite‐based membrane

“…The concept is encouraging; however, the use of these types of systems in high-temperature separation technologies strongly drives the thermal and chemical instability of the solid phase of the membrane, causing eventually, the degradation of the permeation properties. 16,17 Various efforts to solve stability problems and improve permeation in dualphase membranes have included studying the compatibility of different conducting materials with a carbonate phase at elevated temperatures (600-900°C). The development of dense membranes based on silver/Li-K molten carbonates is an example of the work that has been carried out to improve these stability issues.…”
