چکیده انگلیسی
Microporous carbon nano sphere (MCNS) was successfully prepared through the precipitation method of an aromatic isotropic pitch in water without any activation. MCNS was composed of nano spheres with diameter ranging from 100 to 300Â nm, which were interlinked together to form a three-dimensional network in a MCNS particle. There were a number of mesopores among the nano carbon spheres, while micropores were developed within a nanosphere. These structural features enabled MCNS to have high specific capacitance as high as 154Â FÂ gâ1 by cyclic voltammetry (CV) and capacitance per surface area of 0.62Â FÂ mâ2 as an electrode for the inorganic capacitor, respectively.
