Despite its metastable nature, the compound has attracted scientific attention due to its structural diversity. Its role in catalytic processes is a subject of ongoing research, particularly in the context of developing efficient materials for sustainable energy conversion technologies.
Key Properties
Cross-validated computational properties for Mn3TeO8, 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, Mn3TeO8 represents a specialized, less-conventional alternative to the widely characterized spinel and layered structures like LiMn2O4 or LiCoO2. While materials such as LaMnO3 are frequently studied for their robust stability and perovskite-based activity, Mn3TeO8 offers a distinct compositional framework that challenges traditional design paradigms in catalytic material development.
