About Ni3OF5
Ni3OF5 is a semiconducting oxyfluoride that functions within the broader family of oxide oxygen-evolution catalysts. Its unique composition of nickel, oxygen, and fluorine positions it as a subject of interest for researchers investigating non-traditional catalytic surfaces for water splitting and electrochemical energy storage applications. As a metastable phase, this compound offers distinct structural features compared to conventional binary oxides. Its existence in multiple reported structures highlights its potential utility in complex catalytic environments where surface stability and electronic tuning are critical for performance.
Key Properties
Cross-validated computational properties for Ni3OF5, 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.

How It Compares
Within the oxide oxygen-evolution catalysts class.
While common catalysts like NiO and LiCoO2 are widely utilized for their thermodynamic stability and well-understood behavior, Ni3OF5 represents a more specialized, metastable alternative that challenges traditional design paradigms. Unlike the perovskite-structured LaNiO3 or LaMnO3, which are frequently studied for their robust oxygen-evolution activity, Ni3OF5 offers a different chemical landscape by incorporating fluorine, which can significantly alter the electronic environment and surface reactivity of the nickel centers.
