AlFO
AlFO is an insulating, near-hull stable aluminum oxyfluoride compound studied within the context of spinel-type catalytic materials.
About AlFO
AlFO is a wide-gap insulating material that belongs to the broader family of spinel-related oxide catalysts. Its electronic character suggests it functions primarily as a dielectric or structural component within catalytic systems, where its thermodynamic stability near the hull indicates it is a viable target for experimental synthesis.
As a member of the oxide catalyst class, AlFO offers a distinct chemical environment compared to traditional transition metal oxides. Its composition, incorporating both fluorine and aluminum, provides a unique structural framework that distinguishes it from more common spinel structures, making it an interesting subject for materials scientists exploring non-traditional catalytic pathways.
Key Properties
Cross-validated computational properties for AlFO, 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 AlFO. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.

How It Compares
Within the spinel oxide catalysts class.
Unlike the highly active transition metal-based catalysts in its class such as CuO, NiO, or LaMnO3, AlFO acts as a wide-gap insulator, placing it closer in electronic behavior to stable, inert oxides like Al2O3 or MgAl2O4 rather than the redox-active perovskites.
