Using TiO₂ and Ti_0.5Zr_0.5O₂ as carriers, the CuO/TiO₂ and CuO/Ti_0.5Zr_0.5O₂ catalysts were prepared by the impregnation method with Cu (NO₃)₂ as active component. The catalytic activities in NO+CO reaction were investigated using a microreactor-GC system, and structure and reducibility of catalysts were characterized by means of physical adsorption, TPR, XRD, NO-TPD technologies. It was found that the activity of CuO/Ti_0.5Zr_0.5O₂ catalyst was higher than that of CuO/TiO₂, probably due to the large specific surface area of Ti_0.5Zr_0.5O₂ that played an important role in NO+CO reaction.
- Ti_0.5Zr_0.5O₂ solid solution,
- supported CuO catalysts,
- NO+CO reaction.
