Catalytic activity and adsorption properties of carbon nanotubes, which were synthesized on nickel and cobalt oxides, with supported oxide Cu-Co-Fe system were studied. The sample containing nanotubes which were synthesized on nickel oxides, with (10 + 10) mass. % of the active catalytic phase, completely converts CO into СО2 at 47 oС. The high values of the surface area and the volume of mesopores were characteristic of the sample. It was shown that increase of catalytic activity correlates with the quantity of the α2 form of СО2.


Key word carbon nanotubes, oxides, catalysis, carbon monooxide.
