The effect of Ba/K and Sn on soot oxidation and NOx reduction performance over a NSR catalyst was investigated. The addition of Sn lowered teh soot ignition temperature. Both the storage and oxidation capacity seem to be uninfluenced by Sn. During sulfur poisoning and desulfurization, Sn was found to promote desulfurization
