1. Use of a method for the targeted desulfurization of NOx storage catalysts which are used for exhaust gas purification of predominantly lean-burning combustion engines, wherein the NOx storage catalysts comprise cerium and alkaline earth metal-containing nitric oxide storage catalysts in a weight ratio of cerium-containing nitric oxide storage catalysts to alkaline earth metal-containing ones of 10:1 to 20:1, wherein these are desulfurized at ≧500° C. on average in an A/F range of 0.98≦λ≦1.0. |
