摘要：
Herein, uniform core-shell Au-Pd@Pd nanocrystals (Au-Pd@Pd NCs) were prepared by a simple and eco-friendly one-step wet-chemical co-reduction method using allantoin as a structure-directing agent, without using any pre-made seed, toxic organic solvent, surfactant or polymer. Their characterizations were determined by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The possible growth mechanism was also discussed in details. The as-fabricated architecture showed enhanced electrocatalytic ability and stability toward ethylene glycol oxidation reaction (EGOR) as compared to Au nanocrystals and commercial Pd black catalysts in alkaline media.
