· Sr2FeO4

Sr₂FeO₄ is an iron-strontium oxide ceramic compound belonging to the layered perovskite family, primarily investigated for electrochemical and energy-storage applications. This material is largely a research compound studied for oxygen-ion conductivity and catalytic properties, with potential use in solid oxide fuel cells (SOFCs), oxygen separation membranes, and electrocatalysts for water oxidation. Engineers and researchers explore Sr₂FeO₄ variants because the combination of strontium and iron oxides can offer mixed ionic-electronic conductivity and tunable redox activity—properties valuable in high-temperature energy conversion systems where conventional electrolytes face thermal or chemical constraints.
