Comparison

How It Compares

Within the platinum-group alloy catalysts class.

Unlike more thermodynamically stable members of the platinum-group alloy class such as GeRu, FeRu exists above the hull, indicating a higher degree of structural instability. While compounds like As2Pt or IrSe2 are often explored for their specific semiconducting or catalytic niches, FeRu is distinguished by its high structural richness, with over a hundred reported configurations despite its tendency toward instability.
