3D Macroporous Nitrogen-doped Graphene Frameworks for High-Performance Supercapacitors
Published online by Cambridge University Press: 14 March 2014
A novel type of nitrogen-doped hierarchically 3D macroporous CMG films electrode (NCMG) was prepared through a facile ultrafiltration method using graphene oxide (GO) and polystyrene (PS) as precursors, then annealed in N2 atmosphere at 1000°. This NCMG electrode exhibits high specific capacitance (150 F g-1), excellent rate capacity and good cycle life (98% of initial capacitance), which can be a good candidate for supercapacitor application.
