{110}‐faceted alloy nanocrystals : Rhombic dodecahedral Au–Pd alloy nanocrystals (NCs) enclosed exclusively by 12 {110} facets were prepared by a simple one‐pot aqueous synthetic method. The picture shows an SEM image of the NCs (inset: ideal RD structure). The NCs exhibit higher surface‐enhanced Raman scattering and electrocatalytic activities than {111}‐faceted nanoparticles.
