Using TiO2 and Ti0.5Zr0.5O2 as carriers, the CuO/TiO2 and CuO/Ti0.5Zr0.5O2 catalystswere prepared by the impregnation method with Cu(NO3)2 as active component. The catalyticactivities in NO+CO reaction were investigated using a microreactor-GC system, and structure andreducibility of catalysts were characterized by means of physical adsorption, TPR, XRD, NO-TPDtechnologies. It was found that the activity of CuO/Ti0.5Zr0.5O2 catalyst was higher than that ofCuO/TiO2, probably due to the large specific surface area of Ti0.5Zr0.5O2 that played an importantrole in NO+CO reaction.
