Abstract: | Activated carbon anchored by multiwalled carbon nanotubes has been prepared by a simple method and have been reported the effect of various aqueous electrolytes such as KOH and Na 2 SO 4 on electrochemical performance of activated carbon/multiwalled carbon nanotubes composite. The electrochemical performance of as prepared composite has been investigated by cyclic voltammetry (CV) and galvanostatic charge discharge (GCD) measurements in 1M KOH and 1M Na 2 SO 4 aqueous electrolytes. Maximum capacitance of prepared composite was 194 F/g at scan rate of 10 mV/s and 56 F/g at scan rate of 100 mV/s in 1M KOH solutions whereas the composite gives maximum capacitance of 21 F/g at scan rate of 40 mV/s in 1M Na 2 SO 4 analyzed by CV measurement. Also, form GCD measurement the composite gives maximum capacitance of 147 F/g at a current density of 60 A/g in 1M KOH and 18 F/g at a current density of 1 A/g in 1M Na 2 SO 4 solutions. The finding suggests that prepared activated carbon/multiwalled carbon nanotubes composite in suitable aqueous electrolytes can be a potential candidate for supercapacitor applications. |
