Depositing Pt atoms on nanoscale two-dimensional (2D) substrates resulting in the exposure of specific crystal facets is an effective strategy for reducing the Pt content without compromising the catalytic property. Herein, the Pd/PtCu core/shell nanoplates exhibit substantially improved ORR and MOR mass activities, 8.3 and 3.3 times higher than those of commercial Pt. The present work highlights the important role of designing a 2D core/shell nanostructure in enhancing fuel cell electrocatalysis.
