ABSTRACT: Hierarchical porous activated carbon is a superior material in
manufacturing supercapacitors. However, the hierarchical porous structure is
hard to obtain from a single activation method. This work was carried out with
the anticipation of producing activated
carbon by reactivating corn flour with KOH. By employing the electrodes,
the supercapacitor demonstrated a high discharge capacitance (151.2 F·g-1 at 1 A·g-1), and the specific capacitance is with 3.7
times more capacitance than the activated
carbon only through H3PO4 activation. The mechanism of improving the
electrical performance has been discussed through performing SEM, XRD, EIS, and Raman analysis. The
hierarchical porous and disordered structure emerge smaller charge
transfer resistance, and fast electron transfer.
