Controllable synthesis of Pt–Cu nanocrystals and their tunable catalytic properties

Abstract

In this work, Pt–Cu nanocrystals (NCs) with octahedral and multi-octahedral structures were facilely prepared by a wet chemistry method. Furthermore, we have evaluated the catalytic activity of these Pt–Cu NCs, and the results indicated that the composition and morphology strongly influence the catalytic performance in the p-chloronitrobenzene hydrogenation and methanol electro-oxidation reactions, respectively.
