Abstract


  • Nitrogen-doped graphene was successfully synthesised from graphene

    oxide (GO) and 2-methylimidazole composite via thermal treatment under

    argon flow at 700oC within 1h. This synthesised N-doped graphene

    exhibits homogeneous nitrogen doping with concentration of ~5% in

    three different nitrogen configuration namelypyridinic N, pyrrolic N and

    graphitic N. The electric double layer capacitor (EDLC) made up with

    this N-doped graphene showed excellent specific capacitance 274 F/g

    at current density of 1A/g, which was ~7 times higher than GO. This

    EDLC capacitor showed excellent cyclic stability up to 5000 cycles with

    capacity retention of ~91%.
