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

Abstract

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 catalysts were 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 Co 2 O 3 , 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 CO into CO 2 at temperatures below 100°C.
