MnV2O7
MnV2O7 is a semiconducting manganese vanadium oxide studied for its potential utility in oxygen-evolution catalytic reactions.
About MnV2O7
MnV2O7 is a semiconducting oxide that functions within the broader category of oxygen-evolution catalysts. Its composition of manganese, vanadium, and oxygen places it in a specialized class of materials often evaluated for their potential in electrochemical energy conversion processes.
While this compound is currently identified as being above the thermodynamic hull, it remains a subject of interest for researchers mapping the structural landscape of transition metal oxides. Its existence in multiple reported structures highlights the ongoing efforts to characterize complex vanadium-based systems for catalytic applications.
Key Properties
Cross-validated computational properties for MnV2O7, 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.
Unlike highly stable and widely utilized battery cathode materials such as LiCoO2 or LiMn2O4, MnV2O7 represents a more exploratory phase of material design within the oxide catalyst family. While siblings like NiO or LaMnO3 are well-established benchmarks for catalytic performance, MnV2O7 serves as a distinct, less-common variant that helps researchers understand the stability limits and electronic behaviors of manganese-vanadium oxide frameworks.
