Prior to discuss about the electrochemistry of N-doped graphene, it is essential to understand the properties of various doped nitrogen configuration which is beneficial for the progress towards supercapacitor applications. Among the various bonding configuration of N, pyridinic nitrogen is chiefly presumed as responsible for the enhancement in the performance of N-doped graphene for supercapacitor applications. This is because of the fact that the unshared pair of electrons from the pyridinic ring are outside the ring which are easily accessible to the ions in the electrolyte during electrochemical cycling. Therefore, the lewis basic nature of nitrogen represents the basic criteria for the suitability of N-doped graphene in supercapacitor application. When the content of both pyridinic and pyrrolic N is higher then both the basic nature of N-doped RGO as well as the charge density of the graphene increases. If the electrochemistry of highly basic N-doped RGO is performed under acidic medium then the interaction between the more basic N-functionalities and protons from the H2SO4 electrolyte is more pronounced due to the stronger adsorption of H + ions from the electrolyte towards the surface of the electrode. This is in good agreement with the previous report in which the overall specific capacitance of N-doped graphene by microwave route is 233.1 F g -1 in 1 M H2SO4 which is higher than 1 M KOH solution (185. 5 F g -1 ). The drop in the value of specific capacitance in alkaline medium is attributed to the fact that the faradaic interaction between pyridinic N and hydroxide ions are restrained due to the unavailability of H + ions from the electrolyte . The possible electrochemical interactions of different bonding configurations in N-doped graphene in acidic electrolyte is represented as follows:
