NiOF2
NiOF2 is a semiconducting nickel oxyfluoride material that is being studied for its potential role in oxygen-evolution catalytic processes.
About NiOF2
NiOF2 is a semiconducting nickel oxyfluoride compound that falls within the broader category of oxide oxygen-evolution catalysts. Its unique chemical composition, incorporating both oxygen and fluorine anions, makes it a subject of interest for researchers exploring complex transition metal systems for electrochemical energy conversion.
Despite its status as a thermodynamically metastable phase that lies above the hull, NiOF2 remains a notable entry in materials databases. Its existence across multiple reported structures highlights the ongoing effort to stabilize and characterize such oxyfluoride materials for potential use in catalytic environments.
Key Properties
Cross-validated computational properties for NiOF2, 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 NiO or the common layered cathode materials like LiCoO2 and LiNiO2, NiOF2 represents a less conventional and more metastable member of the oxide-based catalyst family. While perovskite-structured siblings such as LaNiO3 and LaMnO3 are frequently studied for their robust catalytic performance, NiOF2 offers a distinct chemical landscape due to the electronegativity of the fluorine substitution, setting it apart from the purely oxide-based members of its class.
