First principles insights into the relative stability, electronic and catalytic properties of core-shell, Janus and mixed structural patterns for bimetallic Pd-X nano-alloys (X = Co, Ni, Cu, Rh, Ag, Ir, Pt, Au).
TL;DR: In this article , the authors analyzed the catalytic activity of eight Pd-related bimetallic nano-alloys and showed that three well-known orderings of the two constituting atomic species in a bimetalloy -core-shell, Janus and mixed structural patterns -may be interconvertible depending on synthesis conditions.
