Title
A novel catalyst of CeO2/Al2O3 for selective catalytic reduction of NO by NH3
Abstract

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.
