A templateless, surfactantless, simple electrochemical route to prepare dendritic gold nanostructure is reported. The morphology, composition, and structure of as-prepared dendritic gold nanostructure were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. The whole nanostructure was constructed by pristine metallic gold. The formation mechanism related to experimental conditions was discussed. The synthesis promises indium tin oxide (ITO) electrode can be easily modified with the dendritic pristine gold nanostructure. The as-prepared modified ITO electrode has excellent catalytic activity to oxygen reduction in neutral KCl solution.
