Key Properties
Cross-validated computational properties for CoSeO3, 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 diverse family of oxide oxygen-evolution catalysts, CoSeO3 occupies a distinct niche compared to traditional transition metal oxides like NiO or complex layered structures such as LiCoO2. While many members of this class, including LaNiO3 and LaMnO3, rely on perovskite-type frameworks to drive catalytic activity, CoSeO3 utilizes its specific selenate-based coordination environment to influence electronic behavior. This structural difference allows it to offer a unique alternative to the more commonly studied lithium-intercalation oxides, providing researchers with a different pathway for optimizing surface reactivity in electrochemical systems.
