MnCO
MnCO is a semiconducting manganese-based oxide that is studied for its potential role in oxygen-evolution catalysis despite its inherent thermodynamic instability.
About MnCO
MnCO is a semiconducting oxide that serves as a subject of interest within the broader category of oxygen-evolution catalysts. Despite its classification, the compound is characterized as being above the hull, suggesting it is thermodynamically unstable under standard conditions. Its electronic properties and structural diversity have made it a point of focus for researchers studying transition metal-based catalytic systems.
Given the interest in its structural behavior, MnCO has been documented across multiple databases with a significant number of reported configurations. While it faces challenges regarding long-term stability, its role in fundamental studies helps researchers understand the complex phase space of manganese-based oxides in catalytic applications.
Key Properties
Cross-validated computational properties for MnCO, 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.
Within the class of oxygen-evolution catalysts, MnCO stands apart from more robust, widely utilized materials like NiO or LaMnO3. While siblings such as LiCoO2 and LiMn2O4 are celebrated for their thermodynamic stability and established roles in energy storage and catalysis, MnCO remains a more elusive, metastable candidate that highlights the diverse electronic landscapes present within this group of oxides.
