About Pt1Ru1Y2
Pt1Ru1Y2 is a complex ternary alloy belonging to the platinum-group metal catalyst class. Characterized by a semiconducting electronic structure, this material represents a unique intersection of noble metal chemistry and rare-earth integration, offering distinct pathways for surface-mediated reactions.
As a metastable phase, it is a subject of significant interest for researchers investigating non-equilibrium material synthesis. Its existence within a diverse landscape of reported structures highlights its potential for specialized catalytic environments where traditional stable alloys may not provide the necessary electronic tuning.
Key Properties
Cross-validated computational properties for Pt1Ru1Y2, aggregated across 2 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.
