Nitrogen is the most versatile heteroatom in carbon matrices.It affects both the physical and the chemical behaviour of carbons already at low concentration(<1.5%)by influencing the electron distribution and thus the electrical,hydrophilic/hydrophobic and catalytic properties.Nitrogen doped carbon materials have a great potential in energy conversation and storage e.g.,as catalyst in the oxygen reduction reaction(ORR)of fuel cells [1].The electrical conductivity of the carbon materials is crucial in these applications.Incorporation of graphene(GR)into the porous carbon matrix can further improve the electrical conductivity without deteriorating their beneficial properties.
