This is a mixed-metal oxide semiconductor compound containing nickel and strontium in a perovskite-related crystal structure. This material belongs to the family of transition metal oxides and is primarily of research interest for its electronic and ionic transport properties. Sr₂NiO₄ and related Ruddlesden-Popper phases are investigated for solid oxide fuel cell cathodes, oxygen reduction catalysis, and other electrochemical applications where the layered perovskite structure enables mixed ionic-electronic conductivity.
