Mg2FeO4
Mg2FeO4 is a semimetallic iron-magnesium oxide that serves as a subject of investigation in the field of oxygen-evolution catalysis.
About Mg2FeO4
Mg2FeO4 is a complex oxide containing iron and magnesium that functions within the category of oxygen-evolution catalysts. Its electronic structure is characterized as near-zero-gap, placing it in the semimetallic regime, which is a notable departure from many typical insulating oxide catalysts.
Due to its position above the thermodynamic hull, this compound is considered metastable, reflecting the synthetic challenges often associated with such iron-based oxides. Despite this, the material has been documented across multiple structural databases, highlighting its interest for researchers studying catalytic pathways in energy conversion.
Key Properties
Cross-validated computational properties for Mg2FeO4, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the highly stable and widely utilized LiCoO2 or LiMn2O4, which are cornerstones of battery technology, Mg2FeO4 exhibits a distinct semimetallic character that differentiates it from the more traditional semiconducting or insulating members of the oxide catalyst class like NiO or BiFeO3.
