In this work, a simple and rapid one-pot wet-chemical approach was developed for large-scale synthesis of bimetallic AuPt alloyed nanochains with hierarchical structures. Metformin was employed as a structure-director in the synthetic process. There was no any premade seed, organic solvent, polymer or special apparatus involved. The characterization techniques included X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning transmission electron microscopy (STEM), and transmission electron microscopy (TEM). The as-fabricated nanocrystals had enlarged electrochemical active surface area (ECSA, 43.87 m(2) g(Pt)(-1)), and exhibited improved electrocatalytic activity and durability for ethanol oxidation reaction (EOR) and methanol oxidation reaction (MOR) using Pt nanochains and commercial Pt black as contrasts.
