Abstract:In situ exsolution of nanoparticles has been reported to be an efficient path to optimize CO 2 electrolysis performance. Herein, a Ce/Co co-doped SrFeO 3-δ (SF) can achieve the co-exsolution of CeO 2 and Co−Fe alloy in 5% H 2 at 800 °C. A small amount (<10%) of Ce-doped SF cannot stabilize the perovskite structure in a reducing atmosphere. Sr 0 . 9 Ce 0 . 1 Fe 0 . 9 Co 0 . 1 O 3 (10Ce10CoF) and Sr 0.95 Ce 0.05 Fe 0.9 Co 0.1 O 3 (5Ce10CoF) as symmetric electrodes of solid oxide electrolysis cells showed an exce… Show more
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.
