Atomic-Distribution-Dependent Electrocatalytic Activity of Au-Pd Bimetallic Nanocrystals

摘要

During the past decade, bimetallic nanocryslals (NCs) with core-shell and alloy structures have attracted tremendous research interest because of their prominent catalytic activities and stabilities over monometallic NCs. Several previous studies have shown that the catalytic performance of bimetallic NCs could be tuned through the modulation of their morphology, size, and composition. For example, control over the morphology of NCs can tailor their catalytic activity and selectivity because the surfaces of NCs are enclosed by specific facets according to their shapes, which play a decisive role in determining the overall catalytic properties of the NCs.
