Key Properties
Cross-validated computational properties for holmium orthoferrite, aggregated across 2 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.
Within the diverse landscape of oxide catalysts, HoFeO3 shares structural similarities with other perovskite-type oxides like LaMnO3 and BiFeO3. While materials such as LiCoO2 and LiNiO2 are primarily recognized for their roles in battery cathode technologies, HoFeO3 is distinguished by its specific orthoferrite framework, which offers a different electronic environment for surface-active oxygen evolution compared to the simpler binary oxides like NiO.
