InPt
InPt is a metallic intermetallic alloy composed of indium and platinum that is studied for its potential in catalytic applications.
About InPt
InPt is a metallic intermetallic compound belonging to the platinum-group alloy catalyst family. Its electronic structure is characterized by metallic behavior, reflecting the strong orbital interactions between indium and platinum atoms. The material is recognized as thermodynamically stable, placing it near the convex hull of stability and making it a viable candidate for experimental synthesis and characterization.
With a significant number of reported structures across various databases, InPt serves as a key reference point for understanding the phase space of platinum-based alloys. Its structural diversity is essential for researchers investigating how atomic arrangement influences catalytic activity and surface reactivity in industrial processes.
Key Properties
Cross-validated computational properties for InPt, 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 InPt. 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, InPt stands out for its structural richness compared to more specialized or binary-limited counterparts like As2Pt or Ga2Ru. While many members of this class are explored for specific hydrogen evolution or oxidation reactions, InPt provides a distinct metallic framework that offers a different electronic environment than the more complex arsenides or selenides in the group.
