Abstract
The decomposition of N2O in the presence of oxygen was studied on Rh/CeO2 and Rh/La2O3–CeO2 catalysts prepared by wet impregnation method. The conversion of N2O decomposition increased as the Rh loading increased, and the Rh-chloride catalyst showed a poor activity than the Rh-nitrate catalyst. XPS and IC/ICP analysis confirmed that the Rh-chloride catalyst's low activity caused since Rh-chloride catalyst had the some RhCl3 species. N2O decomposition rate over Rh/La2O3–CeO2 catalysts decreased as the La loading increased due to the SMSI effect between Rh and CeO2. H2 TPR confirmed that the activity and reducibility of the catalyst were closely related.
