Al2NiPt
Al2NiPt is a metastable, semimetallic intermetallic alloy containing aluminum, nickel, and platinum used in catalytic research.
About Al2NiPt
Al2NiPt is a specialized intermetallic compound within the platinum-group alloy catalyst family. Its near-zero-gap electronic character positions it as a semimetallic material, which is of significant interest for tailoring surface reactivity in catalytic processes.
Despite its metastable nature, the compound has been identified across multiple structural configurations in materials databases. This structural diversity highlights its complex phase behavior and suggests potential for fine-tuning its catalytic performance through precise synthesis methods.
Key Properties
Cross-validated computational properties for Al2NiPt, aggregated across 3 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.
