Abstract
Abstract We show the design of noble Au/Cu bimetallic nanostructures by a gentle solution process. Transmission electron microscopy (TEM), X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS) analysis confirm the presence of both Au and Cu in the Au/Cu bimetallic nanostructures. The Au/Cu catalyst was explored as an efficient electrocatalyst for methanol oxidation with a current density of 5.71 mA/cm 2 at 0.46 V.
