Au2Cd1Pd1
Au2Cd1Pd1 is a semiconducting ternary alloy composed of gold, cadmium, and palladium that exists as a metastable phase within the platinum-group catalyst family.
About Au2Cd1Pd1
Au2Cd1Pd1 is a complex ternary alloy belonging to the class of platinum-group metal catalysts. It exhibits semiconducting electronic behavior, which distinguishes it from the typically metallic nature of many related noble metal alloys. Its structural complexity is evidenced by a significant number of reported configurations within materials databases.
While this compound is currently classified as thermodynamically unstable relative to the ground state, its existence in multiple structural forms highlights the intricate phase space of gold-cadmium-palladium systems. It serves as a subject of interest for researchers investigating the interplay between noble metals and post-transition elements in catalytic design.
Key Properties

How It Compares
Within the platinum-group alloy catalysts class.
Unlike the more stable binary intermetallics in this class such as BaPd or LaRh, Au2Cd1Pd1 occupies a higher energy state on the phase hull, suggesting it is a metastable phase. While compounds like As2Pt or IrSe2 are often explored for their robust catalytic properties, this ternary alloy represents a more exotic and less common structural arrangement within the broader family of platinum-group catalysts.
