AlPt3
AlPt3 is a stable, metallic intermetallic alloy composed of aluminum and platinum that is primarily studied for its potential in catalytic applications.
About AlPt3
AlPt3 is a robust intermetallic compound belonging to the platinum-group alloy catalyst class. Characterized by its metallic electronic nature, it maintains high structural integrity as a thermodynamically stable phase located directly on the convex hull.
This material is of significant interest in catalysis research due to its unique atomic arrangement and the synergistic electronic effects between aluminum and platinum. Its stability and well-documented structural characteristics make it a reliable subject for investigating surface reactivity and catalytic efficiency.
Key Properties
Cross-validated computational properties for AlPt3, 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.
