摘要：

CeO2/Al2O3 catalysts supported on an activated-ceramics have been prepared and characterized by N-2-BET. XRD, TEM and NH3-TPD methods. The effects of reaction temperature and the interactions between CeO2 and Al2O3 on CeO2/Al2O3/ATS for NO selective catalytic reduction with ammonia were studied. Results showed that the catalyst containing 9 wt% Al2O3 and 13 wt% CeO2 has the highest activity in the temperature range 250-350 degrees C at a space velocity of 3000 h(-1), and the selective catalytic reduction of NO over CeO2/Al2O3 may be an Oxidation-Reduction process.
