Cu-Co-Fe Oxide Catalysts Supported on Carbon Nanotubes in the Reaction of CO Oxidation

Cu-Co-Fe oxide catalysts supported on carbon nanotubes were studied in the reaction of CO oxidation. Carbon nanotubes with diameter 20–30 nm and length of several microns were synthesized on oxides of Ni, Co and Fe. The physicochemical properties of these catalystswere determined with X-ray, TPD analysis and nitrogen adsorption-desorption. The data obtained have shown the potential of using carbon nanotubes synthesized on NiO and Co2O3, as a support for Cu-Co-Fe oxide catalysts in the reaction of CO oxidation. The catalytic systems based on these supports give 100% conversion of COinto CO2 at temperatures below 100 graduate C.
