Abstract Chemical oxidation-reduction is a relatively mature method for preparing reduced graphene oxide (RGO) in industry. In this study, graphite was first oxidized using the modified Hummers method, and then the graphene oxide (GO) with lamellar structure could be obtained by spray drying. After that, four types of RGO samples were prepared, respectively, by using vitamin C (VC) chemical reduction, rapid-heating reduction, slow-heating reduction, and combined VC reduction with rapid-heating reduction methods, and the comprehensive physicochemical cha-racterization was carried out. The results show that the reduction method has a significant effect on the morphology, structure, and conductivity of the obtained RGO. By using VC chemical reduction, spherical RGO with large specific surface area and micro-meso hierarchical pore structure could be produced, and it exhibits low reduction degree and conductivity. The layered RGO samples with high reduction degree and good conductivity can be fabricated by thermal reduction, especially the rapid heating would be conducive to the expansion and peeling of RGO and thus effectively improve its specific surface area. When VC reduction and rapid-heating reduction are used in combination, the generated porous spherical RGO possesses high specific surface area and reduction degree, nevertheless, duing to the large contact resistance between RGO particles, its conductivity is inferior to corresponding RGO sheets produced by thermal reduction.
