Hollow NiO nanofibers modified by citric acid and the performances as supercapacitor electrode

---

Abstract.
NiO nanofibers modified by citric acid (NiO/CA) for supercapacitor material have been fabricated by
electrospinning process. The characterizations of the nanofibers are investigated by Fourier transform
infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission
electron microscopy (TEM). Electrochemical properties are characterized by cyclic voltammetry,
galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy. Results
show that the NiO/CA nanofibers are hollow tube and comprised of many NiO sheets. Furthermore, the
NiO/CA nanofibers have good electrochemical reversibility and display superior capacitive performance
with large capacitance (336 F g−1), which is 2.5 times of NiO electrodes. Moreover, the NiO/CA nanofibers
show excellent cyclic performance after 1000 cycles.
