Stabilizing a high-temperature electrochemical silver-carbonate CO2 capture membrane by atomic layer deposition of a ZrO2 overcoat†
Abstract
A high-selectivity and high-flux electrochemical silver-carbonate dual-phase membrane was coated with a nanoscaled ZrO2 layer by atomic layer deposition (ALD) for stable CO2 capture at high-temperature (≥800 °C); the latter has an important implication for direct dry methane reforming with the captured CO2 and O2 for syngas production.
