AlDyO3
AlDyO3 is a stable, insulating oxide material composed of aluminum, dysprosium, and oxygen that is being explored for specialized catalytic applications.
About AlDyO3
AlDyO3 is an insulating oxide that occupies a promising position near the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis. As a member of the broader oxide catalyst family, it leverages the unique electronic properties of rare-earth dysprosium combined with aluminum to form a stable lattice structure.
This compound is primarily investigated for its role in catalytic processes where wide-gap electronic characteristics are beneficial. Its structural versatility, supported by multiple reported configurations, makes it an interesting subject for researchers aiming to tune surface activity and chemical stability in complex oxide systems.
Key Properties
Cross-validated computational properties for AlDyO3, 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 conductive or transition-metal-rich members of its class like LaNiO3 or LaMnO3, AlDyO3 functions as a wide-gap insulator. While it shares structural similarities with the perovskite-like LaAlO3, its inclusion of dysprosium differentiates its chemical potential, positioning it as a distinct alternative to more common spinel-based catalysts such as MgAl2O4 or simple oxides like ZnO.
