Abstract

Highly porous nitrogen doped carbon / activated carbons were synthesised through polycondensation of resorcinol (R) and formaldehyde (F) where nitrogen was incorporated into polymer matrix using melamine as nitrogen source. N-doped carbon / activated carbons were characterised for their physical structure and their electrochemical performance was analysed when used as electroactive material in electrochemical capacitor cell.
Porous parameters of N-doped carbon / activated carbons was characterised by nitrogen adsorption/desorption measurements. There was no significant change in average pore size however enormous increase in specific surface area from 841m2g-1 to 1372 m2g-1 was observed after activation processes at elevated temperature under CO2. N-doped carbon / activated carbons were characterised electrochemically using cyclic voltammetry measurements which showed nitrogen enriched activated carbons (MRFCA) exhibited the improved specific capacitance of up to 289 Fg−1 as compare to 208 Fg-1 of nitrogen enriched carbon (MRFC ) at the scan rate of 5 mVs-1 using 6M KOH electrolyte. Improved capacitive performance of MRFCA can be attributed to the combined effect of the increased specific surface area and extra pseudocapacitance generated due to nitrogen- containing functionalities incorporated into the bulk of the electroactive material.
