摘要

CeO₂/Al₂O₃ catalysts supported on an activated-ceramics have been prepared and characterized by N₂-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 °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.
