Abstract
Hollow graphene-like nanocages are prepared by an efficient and scalable quasi chemical vapor deposition technique. The structure and morphology of the product are investigated by X-ray diffraction, Raman spectrum, scanning electron microscopy, transmission electron microscopy, X-ray photoelectric spectroscopy and nitrogen adsorption-desorption analysis. The supercapacitive performances for the electrode are investigated by cyclic voltammetry and charging-discharging methods. The hollow graphene-like nanocages have a near hollow sphere morphology and nanoporous frameworks. When evaluated for supercapacitor electrode, relatively high specific capacitance of 165.7F/g and 283.1F/g are obtained at current density of 1A/g in 1M KOH and 1M H2SO4 electrolytes, respectively. In addition, desirable rate performance and good cycling stability are also demonstrated for the hollow graphene-like nanocages.
