CrOF3
CrOF3 is a semiconducting oxyfluoride material that belongs to the broader class of spinel oxide catalysts.
About CrOF3
CrOF3 is a semiconducting compound characterized by its unique combination of chromium, oxygen, and fluorine. As a member of the spinel oxide catalyst class, it represents a complex structural arrangement that is of significant interest for fundamental materials research. Due to its position above the thermodynamic hull, this material is considered metastable, which presents intriguing challenges and opportunities for synthetic chemists. Its electronic character suggests potential utility in specialized catalytic applications where semiconducting properties are advantageous.
Key Properties
Cross-validated computational properties for CrOF3, 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 spinel oxide catalysts class.
Unlike the highly stable and widely utilized spinel MgAl2O4 or the robust binary oxides like ZnO and NiO, CrOF3 occupies a more precarious thermodynamic state. While materials like LaMnO3 and LaNiO3 are well-established perovskite catalysts, CrOF3 represents a more exotic, less conventional entry in the broader oxide catalyst landscape, requiring precise control during synthesis to navigate its inherent instability.
