Activated carbon composite was prepared from sugarcane bagasse. The X-ray diffraction revealed the evolution of crystallites of carbon and silica during activation at higher temperature. FTIR spectrum shows the presence of functional groups and silica in the carbon composite. The morphology of the carbon sample was determined by SEM. The surface area, pore volume and pore size distribution of carbon composites were measured. The dc conductivity was determined and conductivity at room temperature was found to increase from 10.22 x 10(-3) to 25.131 x 10(-3) S cm(-1). The samples show good electrochemical property and the specific capacitance in the range of 92-340 F g(-1). (c) 2013 The Korean Society of Industrial and Engineering Chemistry.
