| Abstract |
Nitrogen-doped porous carbon was prepared by carbonization of poly(vinylidene fluoride) (PVDF) using polypyrrole (PPy) as a selective nitrogen source at 800oC (microporous carbon, MC) and KOH activation (activated MCs, A-MCs). The crystal structure and morphologies of MC and A-MC were investigated by X-ray photoelectron spectroscopy and scanning electron microscopy. The porous texture of the samples prepared was analyzed at 77 K for N2 adsorption and 87 K for Ar adsorption. The electrochemical behaviors of samples were performed by cyclic voltammetry and galvanostatic charge-discharge cycling. It was found that A-MC 2 (with a KOH:carbon ratio of 2) exhibits excellent specific surface area, micropore volume, and specific capacitance. |
