A two-dimensional highly ordered mesoporous carbon/graphene nanocomposite for electrochemical double layer capacitors: effects of electrical and ionic conduction pathways
2015
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 m2 g−1 and a large total pore volume of 0.94 cm3 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.
