Abstract:Graphene(GN) was prepared by high temperature(1 050 ℃) oxidation reduction method, using spherical graphite as raw materials, HClO4 as intercalator and KClO3 as oxidant. The structure and properties were characterized by FT-IR, XRD, SEM, TEM, BET and RS. Effect of KClO3 adding amount on the structure and performance of GN were investigated. When the dosage of KClO3 is 0.08 g·mL-1, GN have best performance that the surface area is 558 m2·g-1, the average pore size is 3.012 nm and the resistivity is 0.02 Ω·cm.
