Au2Pt2
Au2Pt2 is a metallic intermetallic alloy composed of gold and platinum that is studied for its potential roles in catalytic applications.
About Au2Pt2
Au2Pt2 is a metallic platinum-group alloy that occupies a significant position within the landscape of intermetallic catalysts. Its electronic structure, characterized by a lack of a band gap, indicates robust metallic conductivity essential for electron transfer processes in catalytic environments.
As a near-hull compound, this material is considered a promising candidate for experimental synthesis. Its presence across multiple structural databases highlights its importance as a subject of ongoing research into the fundamental properties of gold-platinum binary systems.
Key Properties
Cross-validated computational properties for Au2Pt2, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Compared to other platinum-group alloys like As2Pt or Ga2Ru, Au2Pt2 represents a distinct combination of noble metals that balances structural complexity with the catalytic utility typical of the class. While many members of this group, such as IrSe2, often incorporate non-metallic elements to tune their reactivity, Au2Pt2 relies on the synergistic interplay between gold and platinum to define its performance profile.
