Synthesis and Characterization of Dual-Phase Inorganic Membranes

Over a third of CO2 emissions in the U.S can be traced to fossil fuel combustion. The impact of this harmful greenhouse gas can be mitigated with carbon capture and storage technology. Mixed ionic-electronic conducting (MIEC) dual-phase membranes are capable of highly selective CO2 separation at high temperatures and can be used for such capture processes. PSCF (Pr0.6Sr0.4Co0.2Fe0.8O3-δ) and SFT (SrFe0.9Ta0.1O3-δ) are candidate materials expected to have competitive CO2 permeance and superior chemical stability compared to other MIEC materials. Experimental CO2 permeance and conductivity data can be used to characterize these dual-phase membranes and highlight their future applications.
