▎ 摘　　要

Graphene/carbon aerogels (RF) were prepared via a Sol-Gel process in graphene oxide (GO) solution using resorcinol (R) and formaldehyde (F) as carbon precursor. The structure, morphology and pore-size distribution of the samples were characterized by XRD, Raman spectrum, SEM and N-2 adsorption desorption method. The results indicate that graphene can act as nucleation and growth sites for carbon aerogels. At low mass loading level of RF, a macroporous structure is formed, and the structure of carbon aerogels originates from sheet-structure of GO precursor. With increasing the mass of RF, RF carbon aerogel results in dispersed and thickened carbon platelets. At high mass loading levels, carbon spheres are obtained. Meanwhile, with increasing the mass of RF, the specific surface area of the aerogel increases firstly and then decreases, reaching the maximum value of 841 m(2)/g when w(GO)/w(RF)=1 : 50. Electrochemical measurements show that GO/RF-100 has the highest specific capacitance of 169 F/g in 6 mol/L KOH aqueous electrolytes.
