PdPt
PdPt is a stable, metallic alloy of palladium and platinum frequently utilized for its catalytic performance in chemical and electrochemical systems.
About PdPt
PdPt is a metallic alloy composed of palladium and platinum, representing a key member of the platinum-group catalyst family. As a thermodynamically stable phase located on the convex hull, it exhibits robust structural integrity, supported by a significant body of structural data across multiple databases.
This material is primarily valued for its catalytic properties, leveraging the synergistic effects of its constituent noble metals. Its metallic nature ensures efficient charge transport, making it a versatile candidate for chemical processing and electrochemical applications where durability and reactivity are paramount.
Key Properties
Cross-validated computational properties for PdPt, 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.
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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of PdPt. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
