Ge2Ir1Li1
Ge2Ir1Li1 is a semimetallic, thermodynamically stable ternary alloy composed of germanium, iridium, and lithium used in catalytic research.
About Ge2Ir1Li1
Ge2Ir1Li1 is a ternary intermetallic compound classified within the platinum-group alloy catalyst family. Characterized by a near-zero-gap electronic structure, it functions as a semimetal, offering unique charge carrier dynamics relevant to advanced catalytic processes.
As a near-hull phase, the material is considered thermodynamically stable and likely synthesizable under standard laboratory conditions. Its composition, integrating germanium, iridium, and lithium, positions it as a candidate for specialized chemical transformations where precious metal activity is modulated by main-group elements.
Key Properties
Cross-validated computational properties for Ge2Ir1Li1, aggregated across 2 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.
Within the diverse landscape of platinum-group alloys, Ge2Ir1Li1 occupies a niche role compared to more traditional binary systems like GeRu or As2Ir. While siblings such as As2Pt or BaPd often exhibit distinct structural motifs, Ge2Ir1Li1 leverages the specific electronic influence of lithium to tune the catalytic surface properties, distinguishing it from the more conventional transition metal-metalloid combinations found in the rest of the class.
