CdPt is a stable, metallic alloy composed of cadmium and platinum used in catalytic research.
About CdPt
CdPt is a metallic intermetallic compound belonging to the platinum-group alloy catalyst family. As a thermodynamically stable phase located on the convex hull, it exhibits robust structural integrity, making it a subject of significant interest for researchers studying catalytic surface interactions.
Its metallic nature suggests excellent electrical conductivity, which is a key requirement for many electrochemical applications. With numerous reported structures across multiple databases, this compound is well-documented, providing a reliable baseline for investigating the behavior of platinum-cadmium systems in catalytic environments.
Key Properties
Cross-validated computational properties for CdPt, 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 CdPt. 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.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse class of platinum-group alloys, CdPt stands out as a highly stable binary intermetallic, contrasting with more complex or less stable members like As2Pt or Ga2Ru. While many alloys in this group are explored for their specific geometric arrangements, CdPt is notable for its consistent thermodynamic stability, placing it among the more structurally reliable candidates for fundamental catalytic studies compared to the broader, more varied group of transition metal pnictides and chalcogenides.
