New Triclinic Perovskite-Type Oxide Ba₅CaFe₄O₁₂ for Low-Temperature Operated Chemical Looping Air Separation.

ABSTRACT: We present the discovery of Ba₅CaFe₄O₁₂, a new iron-based oxide with remarkable properties as a low-temperature driven oxygen storage material (OSM). OSMs, which exhibit selective and rapid oxygen intake and release capabilities, have attracted considerable attention in chemical looping technologies. Specifically, chemical looping air separation (CLAS) has the potential to revolutionize oxygen production as it is one of the most crucial industrial gases. However, the challenge lies in utilizing OSMs for energy-efficient CLAS at lower temperatures. Ba₅CaFe₄O₁₂, a cost-competitive material, possesses an unprecedented 5-fold perovskite-type A₅B₅O_15-δ structure, where both Fe and Ca
