MnTeO3
MnTeO3 is a metastable, insulating oxide compound investigated for its catalytic properties and structural versatility.
About MnTeO3
MnTeO3 is a complex oxide characterized by its insulating electronic nature and metastable thermodynamic state. As a member of the oxide oxygen-evolution catalyst class, it represents a unique structural arrangement of manganese, tellurium, and oxygen atoms that offers distinct pathways for surface-mediated chemical reactions. Its structural diversity is highlighted by multiple reported configurations across various databases, making it a subject of interest for fundamental materials research. The compound is primarily studied for its potential utility in electrochemical energy conversion systems where stable, non-metallic oxides are required to facilitate oxygen production. Its wide-gap electronic character suggests potential applications in specialized optoelectronic or catalytic environments where charge carrier control is essential.
Key Properties
Cross-validated computational properties for MnTeO3, 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 highly studied and commercially prevalent battery materials such as LiCoO2 or LiMn2O4, MnTeO3 occupies a more specialized niche within the oxide catalyst family. While compounds like LaMnO3 and NiO are frequently utilized for their robust conductivity and catalytic activity, MnTeO3 is distinguished by its metastable nature and insulating properties, which set it apart from the more metallic or semi-conducting perovskite-related oxides in the class.
