AlMoO3
AlMoO3 is a semiconducting, metastable transition metal oxide that is studied for its potential catalytic properties within the spinel oxide family.
About AlMoO3
AlMoO3 is a complex oxide belonging to the spinel-related family of materials. As a semiconducting compound, it exhibits electronic properties that make it a subject of interest for researchers investigating transition metal oxide catalysts. Its structural configuration is characterized by a high degree of complexity, reflected in the multiple distinct structural arrangements documented in materials databases.
Despite its classification, AlMoO3 is considered thermodynamically unstable, as it sits above the stability hull. This energetic status suggests that while it can be synthesized or observed under specific conditions, it remains a challenging target for applications requiring long-term structural integrity compared to more robust oxide phases.
Key Properties
Cross-validated computational properties for AlMoO3, 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 spinel oxide catalysts class.
Within the broader class of spinel and transition metal oxides, AlMoO3 stands out as a more exotic and less stable member compared to highly robust and widely utilized materials like MgAl2O4 or Al2O3. While standard oxides such as NiO or ZnO are staples in industrial catalysis due to their well-defined stability, AlMoO3 represents a more specialized, metastable phase that requires careful synthesis, contrasting with the thermodynamic reliability of perovskites like LaAlO3.
