Galvanic replacement dominates the structure of Pt decorated Cu@Pd nanoparticles. With proper Pt loading, it converts Cu@Pd-Pt from a surface disordered structure to multiple twin particles (MTPS) and gain the highest stability in the oxygen reduction reaction among the experimental samples.

With suitable Pt4+ loading for galvanic replacement, Pt clusters will fill in the defect sites on Ni@Pd–Pt (step 1 and step 2). In this event, the overlap between O2 splitting and hydration kinetics optimize the ORR activity of a Pt cluster decorated Ni@Pd NC.
