| Abstract: | The mixture of Mg Al hydrotalcite and ceria was prepared by coprecipitation, and the Ce containing catalyst was obtained after heat activation. The effects of composition of the catalyst, reaction temperature, O 2, H 2O and SO 2 on the NO+CO reaction were examined. The results showed that, for NO+CO reaction, Ce containing mixed oxides have high activity and excellent hydrothermal stability and can maintain the activity to some extent in the presence of O 2, H 2O and SO 2. |
