▎ 摘　　要

A two-dimensional highly ordered mesoporous carbon/graphene nanocomposite (MCG) was synthesized by replicating a KIT-6/graphene nanocomposite. The MCG exhibited a high Brunauer-Emmett-Teller surface area of 1179 m(2) g(-1) and a large total pore volume of 0.94 cm(3) g(-1). On account of its large surface area and high electrical conductivity with 2D morphology, MCG showed a very high specific capacitance of 276 F g(-1) at 1 A g(-1) and maintained 86% of initial capacitance at 100 A g(-1) in 1.0 M TEABF4/AN.
