Gram-scale synthesis of nanomesh graphene with high surface area and its application in supercapacitor electrodes

Abstract

Graphene that had nanomeshes, only one to two graphene layers, and specific surface areas of up to 1654 m(2) g(-1) was produced on gram-scale by template growth on porous MgO layers. Its unique porous structure gave excellent electrochemical capacitance (up to 255 F g(-1)), cycle stability and rate performance.
