AlSbO4
AlSbO4 is a stable, semiconducting ternary oxide used primarily in the field of advanced catalytic materials.
About AlSbO4
AlSbO4 is a semiconducting oxide that sits firmly on the thermodynamic convex hull, indicating high structural stability. As a member of the spinel-related oxide family, it leverages its specific electronic configuration to facilitate complex chemical transformations. Its robust nature makes it a compelling candidate for high-performance catalytic applications where thermal and chemical durability are essential. By balancing aluminum and antimony within an oxygen framework, this compound offers a distinct electronic environment compared to simpler binary oxides. It is primarily investigated for its potential to drive selective oxidation reactions and other surface-mediated processes in industrial chemistry.
Key Properties
Cross-validated computational properties for AlSbO4, 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 widely utilized binary oxides such as ZnO or NiO, AlSbO4 provides a more complex ternary framework that allows for finer tuning of its semiconducting properties. While MgAl2O4 serves as a classic structural archetype for the spinel class, AlSbO4 distinguishes itself by incorporating the heavier antimony cation, which significantly alters the electronic landscape compared to the more traditional aluminates like LaAlO3.
