摘　　要：用回流法以及后续热处理过程合成了Co3O4/还原氧化石墨烯(rGO)复合物。并对样品的成分、形貌、结构以及电化学性能进行了表征与测试。研究结果表明,当Co3O4与rGO的质量比为87∶13时,复合物比电容达到760F.g-1,并且此复合物表现出较好的循环稳定性。Co3O4/reduced graphene oxide （rGO）composites were successfully synthesized by a mild reflux method following thermal treatments. The composition, morphology, microstructure and electrochemical properties of the as-obtained samples were systematically characterized and investigated. The experimental results indicated that the composite achieved the specific capacitance of 760F . g^-1 at a specific current of 1A . g^-1 when the mass ratio of CoaO4 to rGO was up to 87.13. In addition, the composite showed better cycling stability.
