We prepared a series of self-supported macroscopic C/Ni-fiber hybrid electrodes by catalytic chemical vapor deposition (CCVD) using methane, ethylene, ethanol and n-butanol as carbon sources to embed carbon onto a three-dimensional network of sinter-locked conductive 8 μm-nickel fibers. For the as-prepared hybrid electrodes, the Ni-microfibrous network serves as a current collector and the carbons as ion storage media while the macroporous void space serves as an electrolyte reservoir. We characterized the hybrid electrodes using scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), N2 isothermal adsorption- desorption, cyclic voltammetry and electrochemical impedance spectroscopy. The desalination performance of the C/Ni-fiber hybrids was evaluated as electrodes in a capacitive deionization system. The carbon morphology is dependent on the carbonaceous compounds used in CCVD: carbon nanotubes (CNTs) with fishbone-like structure, CNTs with inclined graphene layers parallel to the tube axis, rod-like
