3D network structure of carbon nanofibers (CNF) chemically cross-linked with reduced graphene oxide (RGO) sheet was successfully prepared by electrospinning a dispersion of polyacrylonitrile (PAN) and graphene oxide (GO) sheets in dimethylformamide followed by heat treatment. Cathodes made with such composites after infused with sulfur (CNF-RGO/S) were able to deliver an initial reversible capacity...
Carbon nanofiber (CNF) was prepared by electrospinning using polypropylene and nickel was coated on the CNF by electroless plating. Then, graphene (Gr) was synthesized on the surface of nickel by chemical vapor deposition. After etching nickel, the Gr/CNF was obtained eventually and then used as a working electrode for the determination of levodopa in the presence of uric acid by cyclic voltammetry...
A highly effective approach was developed for the determination of drotaverine hydrochloride (DRH), based on carbon nanofiber–modified glassy carbon electrode (CNF/GCE). Electrochemical impedance spectroscopy (EIS) measurements reveal significant improvements in the conductivity and compatibility of a modified sensor in comparison to the bare GCE. Carbon nanofiber used as the modifier provides to...
A cobalt sulfide encapsulated within carbon nanotube-carbon nanofiber (Co9S8@CNT-CNF) nanohybrid electrode is designed and prepared. The physicochemical characterization such as X-ray diffraction (XRD) and electron microscopy revealed the formation of Co9S8@CNT-CNF. The specific capacitance of Co9S8@CNT-CNF is 1656 F g−1 at 1 A g−1 with good electrochemical cycle stability (92.6% up to 10,000 cycles)...
