MoPt
MoPt is a thermodynamically stable metallic alloy composed of molybdenum and platinum, frequently studied for its potential in advanced catalytic applications.
About MoPt
MoPt is a metallic platinum-group alloy that occupies a stable position on the convex hull, indicating significant thermodynamic robustness. Its structural versatility is highlighted by a high number of reported configurations across major materials databases, making it a compelling subject for fundamental catalytic research. As a metallic system, it facilitates efficient electron transfer, which is a critical requirement for high-performance catalytic surfaces. The compound serves as a model for understanding how alloying molybdenum with platinum influences surface reactivity and chemical durability in harsh environments. Its stability makes it a reliable candidate for long-term industrial processes where structural integrity under reaction conditions is paramount.
Key Properties
Cross-validated computational properties for MoPt, 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 MoPt. Tight agreement means computed properties can be trusted without re-running calculations.
