Catalytic activity, adsorption properties, and state of surface-chemisorbed particles of carbon nanotubes synthesized on oxides of nickel, cobalt, and iron, with supported oxide Cu-Co-Fe system were studied. The sample consisting of nanotubes synthesized on nickel oxide, with 20 % mass. of active catalytic phase, completely converts CO into СО2 at 470С. The high values of surface area and volume of mesopores were obtained for this active sample. It is shown that Н2О and СО2 are desorbed from surface of low-active samples at different temperatures whereas those from the surface of high-active samples at identical temperatures. The increase in catalytic activity correlates with the quantity of α2- form of СО2.
