Basic characterization of PG. (A) X-ray diffraction, (B) Raman spectroscopy, and (C) Fourier transform Infrared spectroscopy of graphite flakes (black), GO (red) and PG (blue). (D) Measurement of specific surface area. The pore size distribution of PG was calculated using Barrett–Joyner–Halenda method presented in Fig. 2D as an inset at 77 K, pore size 1–4 nm.
