Fabrication and Characterization of Ag@C Nanocables with High Aspect Ratios by Hydrothermal Process

Abstract

Abstract. This paper describes that high-yield Ag/C coaxial nanocables has been obtained via a simple hydrothermal approach through the in situ reaction of Ag+ and glucose in the condition of CTAB. The glucose not only acts as reducing agent but also as carbon source. It was found that high aspect ratio(>400)of nanocables with Ag nanowires core diameter (20-60)nm and various carbon shell thickness had been prepared in large scale with a facile aqueous reduction route at low temperatures for different times. All of the products were characterized in detail by multiform techniques: X-ray diffraction(XRD), transmission electron microscopy(TEM), high-resolution TEM(HRTEM), scanning electron microscopy(SEM), energy-dispersive X-ray spectroscopy (EDX).
