Molybdenum platinum is a binary intermetallic compound composed of molybdenum and platinum. It is primarily studied for its catalytic properties and its potential utility in advanced electrochemical processes.
Overview
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.
Metallic / not reported
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.
