英文摘要	glucose-derived activated carbon (gac)/reduced graphene oxide (rgo) composites are prepared by pre-carbonization of the precursors (aqueous mixture of glucose and graphene oxide) and koh activation of the pyrolysis products. the effect of the mass ratio of graphene oxide (go) in the precursor on the electrochemical performance of gac/rgo composites as electrode materials for electrochemical capacitors is investigated. it is found that the thermally reduced graphene oxide sheets serves as a wrinkled carrier to support the activated carbon particles after activation. the pore size distribution and surface area are depended on the mass ratio of go. besides, the rate capability of gac is improved by the introduction of go in the precursor. the highest specific capacitance of 334 f g(-1) is achieved for the gac/rgo composite prepared from the precursor with a go mass ratio of 3 %.
