AlRu2W
AlRu2W is a semiconducting ternary alloy composed of aluminum, ruthenium, and tungsten that is investigated for its unique electronic properties in catalytic research.
About AlRu2W
AlRu2W is a ternary intermetallic compound categorized within the platinum-group alloy catalysts. Characterized by semiconducting electronic behavior, this material represents a unique intersection of transition metals and aluminum, offering distinct electronic properties compared to traditional metallic catalysts.
Despite its existence in multiple structural configurations across databases, the compound is identified as being above the thermodynamic hull. This suggests that while it can be synthesized, it remains a metastable phase, which is a common trait for complex alloys designed for specific catalytic tuning.
Key Properties
Cross-validated computational properties for AlRu2W, 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 platinum-group alloy catalysts class.
Within the class of platinum-group alloy catalysts, AlRu2W occupies a niche position due to its semiconducting nature, contrasting with more conventional metallic conductors like BaPd or LaRh. While siblings such as GeRu and Ga2Ru are frequently studied for their structural stability, AlRu2W stands out as a more experimental, metastable candidate that challenges standard alloying paradigms.
