CoPt2
CoPt2 is a metallic cobalt-platinum alloy studied primarily for its potential applications in catalytic processes.
About CoPt2
CoPt2 is a metallic alloy composed of cobalt and platinum. As a member of the platinum-group alloy catalyst class, it is characterized by its conductive electronic nature and significant structural complexity, evidenced by its presence across multiple material databases. While it is currently classified as thermodynamically unstable relative to the ground state, its structural variety suggests potential for metastable phases. This makes it an intriguing subject for researchers investigating the influence of composition on catalytic activity and phase stability.
Key Properties
Cross-validated computational properties for CoPt2, 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.
