Key Properties
Cross-validated computational properties for FeO2Sb, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the well-characterized lithium-based transition metal oxides such as LiCoO2 or LiNiO2 that are ubiquitous in battery cathodes, FeO2Sb represents a specialized oxide architecture. While materials like LaMnO3 and BiFeO3 are frequently studied for their complex magnetic or multiferroic properties, FeO2Sb is distinguished by its specific role as a catalyst in oxygen-evolution applications, providing a different chemical pathway compared to the more common nickel- or manganese-based oxides.
