Notes:
Carbon monoxide (CO) is a significant air pollutant produced in incomplete oxidation ofcarbon in combustion. From the viewpoint of environmental protection, it is important that theconcentration of CO gas is lowered in air. Catalysis is proving to be an effective route for removingthis pollutant. Therefore, a design of nano-structured catalysts with high efficiency is required. In thepresent work, we focus on a development of nano-size CuOx-CeO2 catalysts for CO oxidationreaction. To prepare nano-structured Cu loaded CeO2 catalysts, a combined method of theconventional impregnation and ammonium carbonate co-precipitation was examined. Morphology,crystal phase and surface structure of prepared catalysts were characterized using High-ResolutionTransmission Electron Microscopy (HRTEM), Scanning Electron Microscopy (SEM) and PowderX-ray Diffraction (XRD). Catalytic properties of CuOx-CeO2 for CO oxidation were investigated ingas flow reactor system under atmospheric pressure and compared with copper oxide loaded zincoxide. We expected that nano-structured CuOx-CeO2 catalysts could be used for removing COproduced in a wet reforming reaction of fuel cell applications
