CdPd
CdPd is a stable, metallic intermetallic compound composed of cadmium and palladium that functions as a catalyst in chemical synthesis.
About CdPd
CdPd is a metallic intermetallic compound belonging to the class of platinum-group alloy catalysts. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of cadmium and palladium atoms that maintains integrity under various conditions.
This material is of significant interest in catalytic science due to its specific electronic configuration and high structural versatility. With a substantial number of reported structures across major databases, it serves as a foundational subject for understanding how noble metal alloys can be tuned for surface-mediated chemical reactions.
Key Properties
Cross-validated computational properties for CdPd, aggregated across 4 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 CdPd. 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.
