Performance of BaCo0.7Fe0.2Nb0.1O3-δ Membrane under CO2-Containing Atmosphere for CCS Application

Mixed ionic-electronic conducting BaCo0.7Fe0.2Nb0.1O3-δ perovskite is a newly developed promising ceramic membrane material. In this work, the stability and permeability of BaCo0.7Fe0.2Nb0.1O3-δ regarding the special requirements for CCS application are investigated. CO2 would deteriorate the membrane performance by decreasing gradient of oxygen vacancy across bulk and surface carbonatation.
