Seed-mediated synthesis of hexameric octahedral PtPdCu nanocrystals with high electrocatalytic performance

In this work, we present a facile etching–reduction–selective epitaxial growth synergistic strategy to synthesize trimetallic nanocrystals. The methodology demonstrated here provides some general guidelines for the design and fabrication of multimetallic heteronanostructures, which would open up new opportunities for practical fuel cell applications or other chemical reactions.
