|Permanent link:||http://hdl.handle.net/10197/3991||Date:||Jan-2007||Abstract:||Preliminary studies on a series of nanocomposite BaO–Fe ZSM-5 materials have been carried out to determine the feasibility of combining NOx trapping and SCR-NH3 reactions to develop a system that might be applicable to reducing NOx emissions from diesel-powered vehicles. The materials are analysed for SCR-NH3 and SCR-urea reactivity, their NOx trapping and NH3 trapping capacities are probed using temperature programmed desorption (TPD) and the activities of the catalysts for promoting the NH3 ads + NO/O2 → N2 and NOx ads + NH3 → N2 reactions are studied using temperature programmed surface reaction (TPSR).||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2007 Elsevier B.V.||Keywords:||NOx;NH3;SCR;Urea;BaO||DOI:||10.1016/j.apcatb.2005.11.025||Language:||en||Status of Item:||Peer reviewed|
