A novel PtPd@Pt core/satellite nanoassemblies with a PtPd bimetallic core and a dendritic Pt shell was fabricated via a simple yet efficient L-glutamic acid derived self-assembly method. The obtained PtPd@Pt nanoassemblies exhibit the reinforced catalytic performance in the aspect of activity and stability for the oxygen reduction reaction relative to the commercial Pt black.
