MgPd
MgPd is a stable metallic alloy composed of magnesium and palladium that functions as a catalyst in advanced materials applications.
About MgPd
MgPd is a metallic intermetallic compound belonging to the class of platinum-group alloy catalysts. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural configuration that is well-documented across multiple materials databases. Its metallic nature suggests high electrical conductivity, which is a critical trait for catalytic performance in electrochemical environments.
The material is highly significant due to its structural stability and the unique synergy between magnesium and palladium. It serves as a model system for understanding how alloying noble metals with lighter elements can tune catalytic activity and surface reactivity, making it a subject of interest for researchers investigating efficient chemical transformations.
Key Properties
Cross-validated computational properties for MgPd, 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 MgPd. Tight agreement means computed properties can be trusted without re-running calculations.
