Key Properties
Cross-validated computational properties for CaFeO2, 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.
Within the class of oxygen-evolution catalysts, CaFeO2 occupies a distinct space compared to highly studied perovskites like LaMnO3 or BiFeO3. While many of its siblings, such as LiCoO2 or LiNiO2, are primarily utilized in battery cathode applications, CaFeO2 is specifically investigated for its catalytic activity in water splitting and related electrochemical reactions, offering a unique electronic profile that differentiates it from the more conventional lithium-based metal oxides.
