Key Properties
Cross-validated computational properties for Cobalt hydroxide oxide, 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.
Within the class of oxide oxygen-evolution catalysts, CoHO occupies a distinct role compared to more traditional, highly stable battery cathode materials like LiCoO2 or LiMn2O4. While those lithium-based oxides are optimized for reversible ion intercalation, CoHO is specifically valued for its catalytic surface properties, positioning it closer in functional utility to electrocatalytic perovskites like LaMnO3 or LaNiO3.
