Synthesis of Nitrogen Doped Carbon and Its Enhanced Electrochemical Activity towards Ascorbic Acid Electrooxidation

Figure 6

Cyclic voltammograms of different NDC materials: ((a)–(e)) represent the PANI, NDC-1, NDC-2, NDC-3, and NDC-4 in 0.01 M potassium ferricyanide + 0.1 M potassium nitrate solution and ((f)–(j)) represent the PANI, NDC-1, NDC-2, NDC-3, and NDC-4 in 0.01 M of hexaammineruthenium (III) + 0.1 M potassium nitrate solution. Scan rate is 20 mVs⁻¹.
