NbRu
NbRu is a metallic, near-hull stable alloy of niobium and ruthenium that is investigated for its potential utility in catalytic applications.
About NbRu
NbRu is a metallic compound belonging to the platinum-group alloy catalyst class. Its electronic structure is characterized by a lack of a band gap, which is typical for conductive metallic alloys, facilitating efficient electron transfer in catalytic environments.
As a near-hull stable phase, this material is considered highly promising for experimental synthesis. Its structural versatility is highlighted by a significant number of reported configurations across major materials databases, marking it as a subject of interest for fundamental studies in alloy behavior.
Key Properties
Cross-validated computational properties for NbRu, 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.
