At present, attention is given to developing methods of synthesis metal micro- and nanostructures. Metal micro- and nano-structures are widely used in different perspective areas, such as medicine, biology, chemical catalysis, surface treatment and refinement, electro-chemical batteries and others. In this work nickel fibrous structures with roughened surface were synthesized via the reduction of nickel chloride with hydrazine. Fibrous structures consist of submicro- or microfibers with surface covered by nanocones. A method to control the surface morphology and structure of nickel fibrous structures was developed. The structure and morphology of these products were characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Studies show that increasing of concentration of nickel chloride results in increase of roughness of the fibers surface and in increase of the specific surface area. It is shown that current density of the electrodes is stable, so, morphology of the nanostructured electrodes is nondestructive during cycling. The obtained material may have potential and wide applications in batteries and other electrochemical systems.
