Be2PtZn
Be2PtZn is a metastable, semiconducting ternary alloy containing platinum and beryllium that is studied for its unique catalytic potential.
About Be2PtZn
Be2PtZn is a complex ternary intermetallic compound categorized within the platinum-group alloy catalyst family. Characterized by its semiconducting electronic nature, this material represents a unique combination of beryllium, platinum, and zinc, offering a distinct electronic environment compared to standard noble metal catalysts. Due to its position above the thermodynamic hull, this compound is considered metastable, making it a subject of interest for researchers investigating non-equilibrium phase formation. Its existence across multiple reported structures highlights the structural complexity inherent in these specific ternary alloy systems.
Key Properties
Cross-validated computational properties for Be2PtZn, 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.
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.
