LAYERED PLATINUM ON FREESTANDING PALLADIUM NANO-SUBSTRATES FOR ELECTROCATALYTIC APPLICATIONS AND METHODS OF MAKING THEREOF

摘要

Core-shell nanostructures with platinum overlayers conformally coating palladium nano-substrate cores and facile solution-based methods for the preparation of such core-shell nanostructures are described herein. The obtained Pd@Pt core-shell nanocatalysts showed enhanced specific and mass activities towards oxygen reduction, compared to a commercial Pt/C catalyst.
