Compared with a model sample, a commercial LNT exhibits different desulfation behavior, such as re-adsorption. The consequence of re-adsorption is that sulfur is more evenly distributed along the catalyst after mild desulfation. The OSC supplied by ceria-related materials play an important role in re-adsorption.
