Abstract: Disclosed is an NOx storage catalyst in honeycomb form wherein the honeycomb is formed from at least one alkaline earth metal sulfate as precursor compound of the storage material, optionally in combination with the customary concomitant and assistant materials and/or optionally at least one stabilizer. Also disclosed is a process for producing such a catalyst. The catalyst is useful for detoxifying exhaust gases from lean burn engines.
