This work highlights the importance of understanding how spatiotemporal chemistry evolves as a function of reaction parameters and catalyst status to accurately predict LNT performance under relevant conditions. New experimental evidences are presented for phenomena such as NH₃ adsorption and oxidation which can affect the axial distribution of NO_x storage.
