Multimetallic dreamcoat: Core/shell nanoparticles of Pd/Au and Pd/Au/FePt were synthesized with palladium (5 nm diameter), a gold shell (1–2 nm), and a FePt shell (2 nm). The synthetic control allowed the Pd/Au catalytic properties to be tuned by the shell thickness. The synthesis provides an indication for future development of multicomponent nanoparticles for advanced catalytic applications.
