Abstract

The detrimental effect on our environment from CO2 emitted by fossil fuels has become a topic of great concern. One way to reduce environmental degradation is to capture the emitted CO2 from power plants. There are multiple types of carbon capture technologies. Electrochemical carbon capture membranes have gained attention recently due to their low cost and low energy consumption. Mixed electronic and molten carbonate conductor (MECC) are one important type of carbon capture membrane. Previous work has shown that depositing Al2O3 coating on a silver matrix could greatly improve the long term stability of the membrane. In this work, atomic layer deposition (ALD) has been used to coat the silver matrix with Al2O3. Membranes with three different thicknesses of the Al2O3 coating were fabricated and tested and the effects of three different ALD cycles on CO2 and O2 flux have been studied.
