Abstract
The alloy phase behavior of nanoparticle (NP) interfaces has been used to tailor asymmetric growth. Using either Au-Pd core-shell or Au-Au(x)Pd(1-x) core-alloy NP starting materials, the deposition of Ag resulted in asymmetric and symmetric growth respectively. The phase segregation of the interface was confirmed by TEM and electrocatalytic activity.
