Sr1 Fe1 O2

SrFeO₂ is an iron-strontium oxide semiconductor compound belonging to the perovskite or layered oxide family, of primary interest in materials research rather than established commercial production. This material is investigated for its electronic and ionic transport properties in advanced energy applications, particularly in solid-state electrochemistry and catalysis, where mixed-valence transition metal oxides offer potential advantages over conventional alternatives for oxygen reduction, oxygen evolution, and ion conduction at elevated temperatures.
