title: Autoprogrammed synthesis of triple-layered Au@Pd@Pt core-shell nanoparticles consisting of a Au@Pd bimetallic core and nanoporous Pt shell.
abstract: Here we report an autoprogrammed synthesis of unique Au@Pd@Pt triple-layered core-shell structured nanoparticles consisting of a Au core, Pd inner layer, and nanoporous Pt outer shell. The proposed synthesis rationally utilizes the temporal separations of the depositions of Au, Pd, and Pt which affords spontaneously step-by-step formation of triple-layered core-shell colloids. The proposed one-step method is unique in its simplicity and is a significant finding for the facile creation of multilayered nanoarchitectures with designed compositions and desired functions.
