Nb2Ru
Nb2Ru is a metallic niobium-ruthenium alloy that serves as a research subject in the study of platinum-group catalytic materials.
About Nb2Ru
Nb2Ru is a binary metallic alloy composed of niobium and ruthenium. As a member of the platinum-group alloy catalyst class, it exhibits characteristic metallic electronic properties, reflecting the strong orbital hybridization typical of transition metal intermetallics. Its structural complexity is highlighted by a significant number of reported configurations across various databases. While it is categorized as a potential catalyst candidate, its thermodynamic profile suggests it resides above the stability hull. This indicates that the material is likely metastable, requiring specific synthetic conditions to stabilize its phase for experimental investigation.
Key Properties
Cross-validated computational properties for Nb2Ru, 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.
