MnTe2O5
MnTe2O5 is a semiconducting manganese tellurite oxide studied for its potential role as a catalyst in oxygen-evolution reactions.
About MnTe2O5
MnTe2O5 is a semiconducting oxide that sits near the thermodynamic hull, indicating it is a promising candidate for experimental synthesis. Its unique arrangement of manganese and tellurium polyhedra makes it a compelling subject for researchers investigating new materials for electrocatalytic water splitting.
As an emerging member of the oxide oxygen-evolution catalyst class, this compound is being evaluated for its potential to facilitate electrochemical reactions. Its electronic structure and structural stability provide a foundation for exploring efficient, earth-abundant alternatives to precious metal-based catalysts in energy storage and conversion systems.
Key Properties
Cross-validated computational properties for MnTe2O5, aggregated across 4 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.
Unlike the well-established battery cathode materials such as LiCoO2 or LiMn2O4, MnTe2O5 represents a more specialized, exploratory approach to catalysis. While perovskites like LaMnO3 are widely recognized for their catalytic activity, MnTe2O5 offers a distinct chemical environment that may provide unique advantages in specific oxygen-evolution reaction pathways compared to traditional transition metal oxides.
