due to a co-generated exotherm. However, it has been noted that the presence of soot prevents NO x traps from employing their full trapping capacity.

Preliminary studies on a series of nanocomposite BaO-Fe ZSM-5 materials have been carried out to determine the feasibility of combining NO x trapping and SCR-NH 3 reactions to develop a system that might be applicable to reducing NO x emissions from diesel-powered vehicles. The materials are analysed for SCR-NH 3 and SCR-urea reactivity, their NO x trapping and NH 3 trapping capacities are probed using Temperature Programmed Desorption (TPD) and the activities of the catalysts for promoting the NH 3ads + NO/O 2  N 2 and NO xads + NH 3  N 2 reactions are studied using Temperature Programmed Surface Reaction (TPSR).
