| Abstract: | The mixed oxides, including YBa 2Cu 3O 7, LaBa 2Cu 3O 7, LaBaCu 2O 5, La 2BaCu 3O 7, La 4BaCu 5O 12 with perovskite structure, were prepared. The catalysts were characterized by means of chemical analysis, XRD, TPD and TPR method. It was found that they were the active catalysts for the NO decomposition and NO reduction by CO. The existance of Cu 3+ is an important factor to give the catalysts a high activity for the NO reduction by CO. |
