Understanding the storage function of a commercial NOx-storage-reduction material using operando IR under realistic conditions

By Juliette Dupré, Philippe Bazin, Olivier Marie, Marco Daturi, Xavier Jeandel and Frédéric Meunier DOI: 10.1016/j.apcatb.2014.05.027 Highlights A commercial NOx-Storage-Reduction (NSR) material was investigated by operando FT-IR Ionic carbonates at the outer layers of Ba particles were replaced with ionic-like nitrates Covalent species (at surface sites of alumina and ceria) were unimportant for the storage.
