CO2 Electrolysis Cells: Enhancing Electrochemical CO2 Reduction using Ce(Mn,Fe)O2 with La(Sr)Cr(Mn)O3 Cathode for High‐Temperature Solid Oxide Electrolysis Cells (Adv. Energy Mater. 24/2021)

In article number 2100339, Kang Taek Lee, Tae Ho Shin and co-workers design a promising robust ceramic electrode for high-temperature CO2 electrolysis cells with a LaGaO3 based solid oxide electrolyte. The presence of the resulting oxygen vacancy enhancement via Mn and Fe co-doped cerium oxide, Ce(Mn, Fe)O2, mixing with La(Sr)Cr(Mn)O3 perovskite oxide not only provides excellent electrochemical performance but also alleviates issues regarding carbon coking and CO-CO2 chemisorption reactions.
