Abstract

Due to their strong metal/support interaction, their high specific surface area and the absence of pores reducing the diffusion the carbon nanofibres (CNFs) are considered to be promising nanosized catalytic support materials [1]. In present contribution a new method of CNFs synthesis based on a catalytic pyrolysis of butane-propane mixture is proposed. Individual 3d-metals as well as their binary mixtures and alloys were used as catalysts. The CNFs synthesized in this way have the diameters of 8 to 80 nm, and the lengths up to 1 micrometer. All the fibres have curved shapes and the amount of inclusions does not exceed 2-3% after appropriate purification. Additionally to the nanocatalysis application, the use of the CNFs in the field emission cathodes and in the field ion sources is proposed and discussed.
