MnRu
MnRu is a metallic, metastable alloy composed of manganese and ruthenium that is primarily investigated for its catalytic potential.
About MnRu
MnRu is a metallic compound belonging to the platinum-group alloy catalyst class. Its electronic structure is characterized by a lack of a band gap, consistent with its metallic nature and potential for facilitating rapid electron transfer in catalytic environments. While it has been the subject of significant structural investigation across multiple databases, it is considered thermodynamically metastable, existing above the hull in terms of its energy profile.
This material is of interest to researchers studying transition metal alloys for specialized catalytic applications. Its composition leverages the unique properties of manganese and ruthenium to explore new pathways in chemical synthesis and surface science, where metallic conductivity is a prerequisite for performance.
Key Properties
Cross-validated computational properties for MnRu, 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.
