Figure 6

Schematic illustration of the synthetic route of reduced graphene oxide with carbon nanotubes (mentioned here as G/CNTs) after annealing at 200 °C (G/CNTs-200) (a). Raman spectra of studied electrodes (b). CV curves measured at 50 mV/s on rGO, CNT, G/CNT and G/CNTs-200 (c), as well as G/CNT annealed at 300, 600 and 800 °C (G/CNTs-300, G/CNTs-600, and G/CNTs-800, respectively) (d). Specific capacitance of rGO, CNTs, G/CNTs, G/CNTs-200, G/CNTs-300, G/CNTs-600 and G/CNTs-800 as a function of current density (e) (Reproduced with permission of [21]. Copyright Elsevier, 2018).
