Key Properties
Cross-validated computational properties for MnAsO4, 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 broad category of oxide oxygen-evolution catalysts, MnAsO4 occupies a distinct niche compared to more conventional battery-related oxides like LiCoO2 or LiMn2O4. While materials such as LaMnO3 are widely recognized for their perovskite-based catalytic activity, MnAsO4 offers a unique elemental composition that differentiates it from the transition-metal-heavy frameworks found in NiO or La2NiO4.
