In this paper, the ordered mesoporous carbon nanofiber arrays (MCNAs), Nickel–Boron (Ni–B) amorphous alloys, and amorphous Ni–B/MCNAs composite for supercapacitor material have been successfully fabricated by a combination of templating method and chemical reduction process. The porous structure and large specific surface area (1270 m2 g?1) of MCNAs favor the utilization of the active material Ni–B amorphous alloys and interfacial charge transport, and provide short diffusion paths for ions. X-ray diffraction, small-angle X-ray scattering, inductively coupled plasma. Transmission electron micrographs and selected area electronic diffraction were taken to characterize the structure of the ordered MCNAs, Ni–B amorphous alloy, and amorphous Ni–B/MCNAs. Electrochemical properties are characterized by cyclic voltammetry, galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy. The results show that the amorphous Ni–B/MCNAs display superior capacitive performance (733 F g?1) over Ni–B amorphous alloys (562 F g?1) at a scan rate of 5 mV s?1 and a good cycling stability after 1000 cycles.
