摘要：
The catalytic reduction of N2O by CO over Au/TiO2 catalysts prepared by direct anionic exchange method was studied. It has been demonstrated that the amount of Au loading and the calcination temperature of the support have a pronounced effect on the catalytic activity and stability of the Au-supported catalysts. The amount of Au loading was varied from 0.5 to 3 wt.%. Calcination temperature of the TiO2 was varied from 300 to 700 degrees C. The sample with 1 wt.% Au supported on TiO2 calcined at 550 degrees C was the most active in the reaction. The N2O conversion on the sample was complete over the temperature range from 25 to 250 degrees C. (C) 2011 Elsevier B.V. All rights reserved.
