LNT are sensitive to sulfur poisoning. The interactions of sulfur with LNTs can be quite complex, owing to their multi-component, topologically complex structure. In this study, we have investigated SO2 interaction with a LNT catalyst and were able to reconcile the unexpected experimental findings with the structure of the catalyst.
