This study demonstrates a facile and effective approach nitrogen doped carbon nanofibers through the electrospinning of blending polyacrylonitrile and polyvinylpyrrolidone with carbonization method. The structure and morphology of as prepared materials are characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and FT-IR spectrometer. The electrochemical measurements are conducted by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge/discharge. As increasing temperature in carbonization, The aspect of nitrogen contents, structures and electrochemical properties were changed. |
