Design of nano-structured Cu loaded CeO2 catalyst for CO oxidation

For CuO-CeO2 catalyst ultra fine particle CeO2catalyst with large specific surface area has been requested from the view point of CO oxidation action. Manufacturing of CeO2 nanopowder by means of the soft chemical method is examined. CeO2 nanopowder is synthesized by the ammonia carbonate coprecipitation method, thenCuO nanotubes are mounted on the powder by the lower temperature calcinations to fabricate nanostructure Cu mounting CeO2 catalyst . TEM,SEM and XRD analysis result of the structure of this catalyst are shown. The organization of developed nanosize Cu on CeO2 is confirmed. This kind of catalyst seems to be a powerful oxidation catalyst.
