Key Properties
Cross-validated computational properties for Cobalt tungstate, 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.
Unlike the lithium-based intercalation oxides such as LiCoO2 or LiMn2O4, which are optimized for ion mobility in battery cathodes, CoWO4 is specialized for catalytic surface reactions. While it shares the oxide classification with materials like NiO and LaMnO3, its tungsten-based framework provides a distinct electronic environment that differentiates its catalytic mechanism from the transition-metal-only oxides in the group.
