제목 Facile synthesis, characterization, and electrochemical behaviors of nitrogen-doped porous carbon for active material of supercapacitor electrode
초록 Nitrogen-doped porous carbon was prepared by pyrolysis 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 characterization of MC and A-MC was investigated by X-ray photoelectron spectroscopy and scanning electron microscope. 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 measured by cyclic voltammetry and galvanostatic charge-discharge. It was found that the nitrogen-doped microporous carbon was prepared successfully by carbonization and activation of PVDF/PPy materials and A-MC 2 (with a KOH:carbon ratio of 2) exhibits excellent specific surface area, micropore volume, and specific capacitance.
