Abstract
Compared with their high ORR activity, the stability of PtCu octahedral nanoparticles is not satisfied, which is hindered by the diffusion/ dissolution of low-coordinated Pt atoms at the defect sites. The trace Au atoms preferentially protects these Pt atoms and inhibits the diffusion/dissolution of these Pt atoms, which is helpful for the maintenance of the shape and thus might promise a high stability.256
