Abstract
Pt, Pd and Rh ammine cations partially ion-exchanged for alkali ions of X and Y zeolites were decomposed in vacuum to metallic clusters embedded in cavities. The course of the parent ammine decomposition as well as the CO + NO reaction after the deammination to metallic clusters were compared for the individual metals. The effects of the respective metals as well as as those of the zeolitic matrices are discussed.
Keywords: Zeolites; Pt, Pd, Rh/alkali faujasites; Ammine ligand decomposition; NO + CO reaction; Heterogeneous catalysis.
