摘要：
The paper deals with ceria-zirconia supported copper catalysts in NO reduction by toluene. Catalysts were characterized by XRD and H-2-TPR. The deNO(x) temperature window was estimated by NO-TPD experiments which revealed two NO desorption areas. The activity and temperature range for deNO(x) reaction were being observed during temperature programmed deNO(x) reaction (TPSR) in the presence of toluene. NOx decomposition, starting above 200 degrees C, was accompanied by total oxidation of toluene. Catalytic tests performed in stationary conditions revealed that the most active in C7H8-SCR of NOx is Cu(4)/CeZrO2. (C) 2011 Elsevier B.V. All rights reserved.
