A simple method to synthesize carbon nanofibers with a parallel growth mode and their capacitive properties

关键字:carbon nanofiber; capacitive property; synthesis

摘要:Carbon nanofibers with a parallel growth mode were synthesized by a chemical vapor deposition (CVD) method using a nickel catalyst precursor and acetylene carbon source gas at 550 degrees C, the growth mechanism and growth model of which were discussed and established, respectively. In the case of no pretreatment, the Brunauer-Emmett-Teller (BET) surface area and total pore volume of the as-synthesized carbon nanofibers were 214m(2).g(-1) and 0.36cm(3).g(-1), respectively. The maximum specific capacitance of the carbon nanofibers was 205.8 F.g(-1), examined at a 0.20 V.s(-1) sweep rate. The structure and morphology of the carbon nanofibers were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and x-ray powder diffraction (XRD).
