AsRu
AsRu is a metallic, metastable platinum-group alloy used primarily in catalytic research and materials science applications.
About AsRu
AsRu is a metallic compound belonging to the platinum-group alloy catalyst class. As a metastable phase, it represents a specialized structural configuration that offers unique catalytic potential for researchers investigating high-performance materials.
Its metallic character ensures efficient electron transport, which is a critical feature for catalytic activity. Given the high volume of structural data available for this compound, it serves as a significant subject for studies focused on the stability and reactivity of ruthenium-based binary systems.
Key Properties
Cross-validated computational properties for AsRu, aggregated across 4 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 platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloys, AsRu occupies a distinct niche compared to more common members like GeRu or Ga2Ru. While many of its siblings exhibit varying degrees of thermodynamic stability, AsRu is notable for its metastable nature, providing a different structural pathway for catalytic interactions than the more robustly studied intermetallic phases.
