FeCO
FeCO is an insulating, metastable iron-based oxide that serves as a research subject in the study of oxygen-evolution catalysts.
About FeCO
FeCO is an inorganic compound categorized within the oxide oxygen-evolution catalyst class. As a wide-band-gap insulator, it exhibits distinct electronic properties that differentiate it from the metallic or semi-metallic conductors typically favored for high-performance catalytic applications. Its structural complexity is highlighted by a significant number of reported configurations despite its tendency to exist in a metastable state.
Because it resides above the thermodynamic hull, FeCO is considered inherently unstable under standard conditions. This makes it a subject of intense fundamental interest for materials researchers studying phase transitions and synthesis pathways. Its role in the broader landscape of oxygen-evolution materials is primarily focused on understanding how iron-based coordination environments influence catalytic activity.
Key Properties
Cross-validated computational properties for FeCO, 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 the highly stable and widely utilized battery cathode materials such as LiCoO2 or LiMn2O4, FeCO is characterized by its relative thermodynamic instability. While siblings like BiFeO3 are well-recognized for their multiferroic properties and structural robustness, FeCO serves as a more elusive member of the oxide class, offering a unique case study in the challenges of stabilizing iron-based systems for energy conversion.
