NiPd
NiPd is a metallic, metastable alloy of nickel and palladium used primarily in catalytic research and materials science applications.
About NiPd
NiPd is a metallic alloy composed of nickel and palladium, belonging to the class of platinum-group alloy catalysts. As a metastable material, it represents a specialized configuration of transition metals that is frequently studied for its unique surface reactivity and structural properties. The material is characterized by its lack of a band gap, confirming its metallic nature. Researchers investigate this compound to understand how combining these specific elements influences catalytic pathways in chemical processing. Its structural diversity is highlighted by numerous reported configurations across multiple databases, reflecting its significance in materials science research. This alloy is primarily utilized in experimental catalysis, where its electronic environment is leveraged to optimize reaction kinetics for various industrial and laboratory applications.
Key Properties
Cross-validated computational properties for NiPd, 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
