BiMnO3
BiMnO3 is a metastable semiconducting oxide used in research for its potential role in oxygen-evolution catalytic processes.
About BiMnO3
BiMnO3 is a semiconducting oxide that exists in a metastable state, making it a subject of significant interest for researchers exploring complex transition metal oxides. Its unique electronic configuration and structural flexibility allow it to function within the broader landscape of catalytic materials, particularly where oxygen-evolution processes are concerned.
This compound represents a specialized niche in oxide chemistry, where its metastable nature provides a distinct pathway for studying catalytic activity. It is primarily utilized in experimental material science research to understand how bismuth-based perovskite-like structures can influence electrochemical reactions.
Key Properties
Cross-validated computational properties for BiMnO3, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of BiMnO3. Tight agreement means computed properties can be trusted without re-running calculations.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse group of oxygen-evolution catalysts, BiMnO3 occupies a distinct position compared to more conventional materials like NiO or LiCoO2. While many of its siblings, such as LaMnO3 or BiFeO3, are well-established perovskites, BiMnO3 is characterized by its metastability, which sets it apart from the more thermodynamically stable oxides commonly used in industrial applications.
