The TEM analysis of SA-GO (which is prepared by the reactions of octadecylamine and the sulfur-doped graphene oxide; the oxidation time of the graphene oxide is 24 h). Including the stacked SA-GO (a), the high-resolution TEM image of the square zone marked in a (b), the dispersed SA-GO (c), the SAED diffraction pattern of the square zone marked in c (d), and the crystalline space analysis of the position marked in b (e)
