Abstract:
This paper presents the results of studies of carbon nanostructures obtained by the laser ablation
of a nanofibrous carbon formed in the process of a catalytic decomposition of hydrocarbons in the presence
of highpercentage catalysts containing the iron subgroup of metals. A continuous CO2 laser with a radiation
density of 3.4 W/cm2 was used in the experiments. The target was placed on a cooled copper substrate in a
helium medium under a pressure of 770–780 torr. Upon the impact of laser radiation, the carbon evaporated
and, further, condensed on the surface of a special condenser. The samples were collected from the condenser
surface and the target in the radiationexposed area. The products were studied by high resolution transmis
sion electron microscopy using a JEM2010 electron microscope. A number of samples underwent a local
energy dispersion Xray microanalysis on the EDAX spectrometer. Multilayer nanotubes of diameters 14–
40 nm and lengths of up to 2 µm have been found in the evaporated and condensed carbon materials. It was
established that part of the nanotubes was filled by the catalyst metal. Interestingly, in the target area exposed
to the radiation, the initial material comprising carbon nanofibers with the structure of inserted cones trans
formed into carbon nanotubes (CNTs) with an average crosssection size of 20 nm.
