Technical Examples

The present invention provides a catalyst for use in a NOx trap that has reduced NOx release during rich purges, increased NO conversion efficiency under stoichiometric conditions, and improved sulfur tolerance. The catalyst of this embodiment includes a precious metal, an oxygen storage component in contact with the precious metal, and a NOx storage material. The oxygen storage component in contact with the precious metal is present in an amount that provides sufficient oxygen storage capacity to reduce the NOx release from the NOx trap during rich purges to less than 20% of the NOx that is stored in the NOx trap across the operating temperature window of the NOx trap, increase the NOx conversion efficiency under stoichiometric conditions to a value greater than 70%, and increase the sulfur tolerance of the NOx trap.
