In2PdRh
In2PdRh is a metastable, semiconducting intermetallic alloy composed of indium, palladium, and rhodium, primarily investigated for its potential in catalytic research.
About In2PdRh
In2PdRh is a specialized intermetallic compound categorized within the platinum-group alloy catalyst class. As a semiconducting material, it represents a unique electronic configuration that distinguishes it from the typically metallic nature of many related noble metal alloys. Its existence in multiple reported structures highlights ongoing interest in its potential for catalytic applications despite its thermodynamic status as an unstable phase relative to the ground state.
Because it resides above the stability hull, In2PdRh is a metastable candidate that requires precise synthesis conditions to stabilize. Its role as a semiconductor suggests potential utility in niche catalytic processes where electronic band structure plays a critical role in surface reactivity and charge transfer mechanisms.
Key Properties
Cross-validated computational properties for In2PdRh, aggregated across 3 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.

How It Compares
Within the platinum-group alloy catalysts class.
Unlike more robust and thermodynamically stable members of the platinum-group alloy class such as IrSe2 or GeRu, In2PdRh is characterized by its metastability. While many siblings in this group are primarily metallic, In2PdRh stands out for its semiconducting electronic character, positioning it as a distinct alternative to the more conventional metallic catalysts like BaPd or LaRh.
