NiPt
NiPt is a stable, metallic alloy of nickel and platinum used as a catalyst in chemical and materials engineering applications.
About NiPt
NiPt is a metallic alloy composed of nickel and platinum, belonging to the class of platinum-group alloy catalysts. Its position on the convex hull indicates that it is a thermodynamically stable phase, making it a robust candidate for research into catalytic performance and structural durability. The material is characterized by its metallic electronic nature, lacking a band gap, which facilitates efficient electron transfer in various chemical environments. Given its extensive documentation across multiple structural databases, it serves as a well-characterized model system for understanding bimetallic interactions. It is primarily utilized in advanced catalytic applications where the synergistic effects of nickel and platinum can enhance reaction pathways and material longevity.
Key Properties
Cross-validated computational properties for NiPt, 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 NiPt. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
