Abstract: In this study,two dimensional nanostructured carbon materials were prepared through inorganic and organic hybrid method that glucose was intercalated into the laminates of iron(III) chloride hexahydrate. The obtained hybrid composite was then thermally carbonized and followed by acid etching. The microstructure and composition of the samples were characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),thermogravimetric analysis (TG),X- ray diffraction(XRD),Ramanspectra and other characterization methods. A three electrode system was used to evaluate the electrochemical properties of the two-dimensional carbon materials and 6 mol/L KOH was used as electrolyte. The results showed that at 0. 5 A/g current density,the mass specific capacitance of the prepared two-dimensional carbon material electrode was up to 236 F/g. When current density increased to 10 A/g,the specific capacitance could still be maintained at 201 F/g,and the specific capacitance retention rate was 85. 2%,this indicated a good rate performance. In addition,the electrode also exhibited excellent cycling stability,which still maintained the initial specific capacitance after 1 000 cycles at a current density of 10 A/g.
