a TEM and HRTEM (inset) images of OPC-CDs-700 show that CD still distributes on OPC after high-temperature treatment. b GCD curves of OPC-CDs-700 at 0.1 A g−1 with/without light illumination. c Specific capacitance at different current densities of OPC-CDs-700 with/without light illumination indicates that OPC-CDS-700 exhibits higher photo-enhanced capacitance under illumination. d The cycling stability of the OPC-CDs-700 electrode by charge–discharge measurement at 1 A g−1 in dark condition and light illumination (inset) indicates that the OPC-CD-700 electrode exhibits good stability.
