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 (Pr_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ) and SFT (SrFe_0.9Ta_0.1O_3-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.
