About FePRh
FePRh is a metallic compound composed of iron, phosphorus, and rhodium. As a member of the platinum-group alloy catalyst family, it is characterized by its conductive electronic structure and is primarily investigated for its catalytic properties in complex chemical reactions. The material exhibits a complex structural landscape, with multiple reported configurations across various databases. While it is categorized as a metastable phase that sits above the thermodynamic hull, its structural diversity makes it a subject of interest for researchers exploring unconventional alloy phases.
Key Properties
Cross-validated computational properties for FePRh, 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.
