(a) Schematic for the preparation of thermally treated activated reduced graphene oxide (TArGO) powder. (b)–(d) Scanning electron microscopy images of GO and ArGO after the thermal treatment of ArGO particles. (e) X-ray diffraction patterns of graphite, GO, ArGO, and TArGO. (f) N2 adsorption–desorption isotherms of graphite, GO, ArGO, and TArGO at 77 K. The inset shows the pore size distributions of GO, ArGO, and TArGO calculated using the BJH method.
