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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
