Au2Rh1Y1
Au2Rh1Y1 is a semimetallic ternary alloy composed of gold, rhodium, and yttrium, primarily studied for its potential roles in advanced catalytic applications.
About Au2Rh1Y1
Au2Rh1Y1 is a complex intermetallic compound belonging to the class of platinum-group alloy catalysts. Characterized by its near-zero-gap semimetallic electronic structure, this material represents a specialized configuration of gold, rhodium, and yttrium atoms designed for catalytic research. Its structural complexity is evidenced by the numerous reported configurations found within materials science databases.
While its thermodynamic profile places it above the hull, suggesting potential instability under ambient conditions, it remains a subject of interest for understanding phase stability in ternary alloy systems. Its role is primarily centered on exploring the fundamental interactions between precious metals and rare-earth elements in catalytic environments.
Key Properties

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloy catalysts, Au2Rh1Y1 occupies a niche position compared to more stable, binary counterparts like LaRh or As2Pt. Unlike the more robust members of this class, its positioning above the hull highlights the challenges in synthesizing and maintaining ternary phases that incorporate both noble metals and yttrium, distinguishing it from the more commonly studied binary intermetallics.
