Preparation and Electrochemical Characteristics of Nitrogen-Doped Mesoporous Carbon Using Surfactants as Carbon Source
Nitrogen-doped mesoporous carbons (NMC) were prepared through a facile procedure using surfactants (polyvinylpyrrolidone) as a nitrogen-containing carbon source. The NMC samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and nitrogen sorption at 77 K. Cyclic voltammetry and galvanostatic charge/discharge experiments were adopted to investigate their electrochemical behaviors. The NMC-5 sample contain abundant mesopores shows the large specific capacitance up to 276 F g−1 at the current of density of 0.1 A g-1. We suggest that the nitrogen-doped mesoporous carbon has potential application as electrochemical capacitor electrode materials.
