LuRu
LuRu is a thermodynamically stable metallic alloy formed from lutetium and ruthenium that is frequently studied for its structural and catalytic properties.
About LuRu
LuRu is a metallic binary alloy composed of lutetium and ruthenium. As a member of the platinum-group alloy class, it exhibits robust thermodynamic stability, sitting directly on the convex hull, which suggests high structural integrity for demanding chemical environments.
This material is characterized by its metallic electronic nature, making it a subject of interest for researchers studying electron-rich catalytic surfaces. With numerous reported structures across multiple databases, it represents a well-documented system for exploring intermetallic bonding and catalytic potential.
Key Properties
Cross-validated computational properties for LuRu, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloys, LuRu stands out for its high stability compared to more complex or metastable phases like Ga2Ru or GeRu. While materials such as LaRh share similar intermetallic characteristics, LuRu offers a unique combination of rare-earth and transition metal constituents that distinguishes its electronic landscape from pnictide-based siblings like As2Pt or As2Ir.
