IrRhZn2
IrRhZn2 is a semiconducting ternary alloy of iridium, rhodium, and zinc investigated for its potential catalytic properties.
About IrRhZn2
IrRhZn2 is a complex ternary alloy composed of iridium, rhodium, and zinc. As a member of the platinum-group alloy catalyst family, it exhibits semiconducting electronic properties that distinguish it from the more metallic members of its class. Its structural complexity is highlighted by its multiple reported configurations across various databases.
While the compound is currently characterized as being above the thermodynamic hull, its existence in multiple structural forms suggests significant interest in its potential catalytic behavior. Research into such metastable phases is vital for understanding how specific atomic arrangements can be stabilized to unlock unique surface reactivity for chemical transformations.
Key Properties
Cross-validated computational properties for IrRhZn2, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Unlike the more common metallic phases found in the platinum-group alloy class, such as LaRh or BaPd, IrRhZn2 occupies a distinct niche due to its semiconducting nature. While many siblings like As2Ir or As2Pt are studied for their robust stability, IrRhZn2 represents a more unconventional, metastable member that challenges standard design principles for high-performance catalysts.
