英文摘要: Large-scale(phi = 10 cm) graphene paper (GP) was prepared by the reduction of graphite oxide paper(GOP) self-assembled at the liquid/air interface with hydrazine hydrate vapor. The morphology, structure, components and BET surface area of GOP and GP were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and nitrogen adsorption-desorption analysis. Furthermore, influence of reduction and reduction temperature on the super-capacitive properties was investigated. It is found that the graphene paper fabricated at 150 degrees C exhibits high capacitive behavior and long charge/discharge cycle life at a current density of 1000 mA/g. The discharge capacitance of the material in an aqueous electrolyte of 6 mol/L KOH is 142 F/g and the capacitance retention is 99.8% after 1000 charge/discharge cycles.
