CoRu
CoRu is a metallic binary alloy of cobalt and ruthenium primarily studied for its potential applications in catalytic science.
About CoRu
CoRu is a metallic binary alloy composed of cobalt and ruthenium. As a member of the platinum-group alloy catalyst class, it is characterized by its conductive electronic nature, which is typical for intermetallic systems of this type. The material has been identified in numerous structural configurations across various databases, highlighting significant interest in its atomic arrangement despite its status as a thermodynamically unstable phase. Its potential utility lies in the unique synergistic effects between the transition metal components, which are often leveraged to tune catalytic activity in chemical processing. While its thermodynamic profile suggests it may be difficult to synthesize in a perfectly stable form, it remains a subject of investigation for those studying high-performance catalytic surfaces.
Key Properties
Cross-validated computational properties for CoRu, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CoRu. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloys, CoRu occupies a niche position alongside materials like GeRu and Ga2Ru. Unlike more stable or common binary intermetallics, CoRu is frequently examined for its structural complexity, reflecting the broad range of phases found in transition metal combinations that, like P3Ru or BaPd, challenge standard thermodynamic predictions.
