Carbon-coated nickel oxide nanofibers (NiC NFs) were fabricated using vapor deposition polymerization on electrospun nickel oxide nanofibers (NiO NFs), followed by carbonization. To decorated the surface with carbon, the NiO NFs as starting materials were prepared by electrospinning a nickel oxide precursor contained a PVP solution and calcining the electrospun NFs. Then, polypyrrole (PPy)-coated NiO nanofibers (NiP NFs) were fabricated as intermediate materials using the pyrrole monomer in the VDP method. As a result, carbonization of the NiP NFs converted the PPy into carbon and thereby formed the NiC NFs. The electrochemical results show that NiC NFs with a thin coating had a higher specific capacitance and longer cycle stabilization than pristine NiO NFs. Here, the synthetic method is an facile route to obtain hybrid core (inorganic)/shell (organic) nanostructures for electrochemical applications. |
