چکیده انگلیسی
Four activated carbon (AC) samples prepared from rice husk under different activation temperatures have been characterized by N2 adsorption-desorption isotherms, thermogravimetric analysis (TGA-DTA), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The specific surface area of AC sample reached 2681 m2 gâ1 under activation temperature of 800 °C. The AC samples were then tested as electrode material; the specific capacitance of the as-prepared activated carbon electrode was found to be 172.3 F gâ1 using cyclic voltammetry at a scan rate of 5 mV sâ1 and 198.4 F gâ1 at current density 1000 mA gâ1 in the charge/discharge mode.
