Figure 3

(a) Representative cyclic voltammogram (CV) curves of graphene oxide (GO) films, photoreduced graphene oxide (PRGO) films and chemically converted graphene (CCG) films at a scan rate of 50 mV s−1, (b) CV curves of PRGO films at different scan rates. Even if the scan rate is increased to 1000 mV s−1, the CV curve basically maintains the Faradaic peak-incorporated rectangle-like shape, indicating the high rate capability of PRGO films. (c) CV curves of PRGO films for different illumination times. (d) Calculated specific capacitances from the CV curves at different scan rates of different samples. (e) Nyquist plots of PRGO films, GO films and CCG films; the inset shows the electrical equivalent circuit used for fitting the impedance spectra. (f) The magnified high-frequency regions of the Nyquist curves.
