N2 - Fe-ZSM-5 catalysts, prepared by different methods, have been characterized by TPR and XRD and tested in the NO-SCR by NH 3. The sublimation method leads to the most active catalysts. Nevertheless the preparation starting from Fe(acac) 3, which is a preparation easy to implement from an industrial point of view, seems to be a very attractive alternative way. On the most active catalyst, Fe(0.83) subZSM-5, prepared starting from FeCl 3, a study of the mechanism was undertaken. In the initial step of the SCR reaction, the oxidation of NO in NO 2, the re-oxidation of Fe II species in the active iron oxo species is the slow phase.
