The presence of ceria improved NO x storage capacity in the temperature range 200-400°C under both continuous lean and lean-rich cycling conditions. Temperature-programmed experiments showed that NO x stored in the ceria-containing catalyst was thermally less stable and more reactive to reduction with both H2 and CO as reductants, albeit at the expense of additional reductant consumed by reduction of the ceria. These findings demonstrate that the incorporation of ceria in LNTs not only improves NO x storage efficiency but also positively impacts LNT regeneration behavior.
