Fine Tuning of the Structure of Pt–Cu Alloy Nanocrystals by Glycine‐Mediated Sequential Reduction Kinetics

Abstract

Uniform Pt-Cu alloy nanocrystals in the shape of dendrite, yolk-cage, and box structures are prepared via a facile wet-chemical reduction route in which glycine is demonstrated to alter the reduction kinetics of metal cations, critical to the morphology of the obtained product. These alloy nanocrystals exhibit superior specific activity and stability in the electro-oxidation of methanol.
