Abstract
Catalytic properties of systems composed of copper loaded CeO2 and SnO2 were examined. Catalysts were prepared using a conventional impregnation method. After preparation the samples were calcined in oxygen respective reduced in hydrogen. Treatments were carried out at 400 oC resp. 300 oC for 2 hours. The amount of copper in prepared samples was 8 at. % in both cases. Morphology and particle size were observed using Scanning Electron Microscopy (SEM). Crystal phases were characterized by X-Ray Diffraction method (XRD). The CO oxidation reaction was performed in a flow micro-reactor in the mixture of He, O2 and CO, where the catalyst was deposited on a silicon oxide chip ensuring a very reliable catalyst temperature control. It can be expected that nano-structured copper loaded oxide catalysts could be used for removing CO produced in a wet reforming reaction for fuel cell applications.
