Supercapacitive properties of composite obtained after different reaction times (1, 4, and 8 h). (a) CV curves recorded in 4 M NaOH solution at 20 mV · s-1; (b) corresponding specific capacitance as a function of scan rate; (c) charging-discharging curves at 1 A · g-1current density; (d) corresponding specific capacitance as a function of current density.
