Abstract

Preparation of a Fe-mordenite catalysts was carried out by impregnation using Fe(acac)3 precursor in order to have iron oxide species deposited at the surface of the zeolite. The selective presence of iron oxide species was determined and ascertained by temperature programmed reduction (TPR). In the selective catalytic reduction of NO by ammonia, no difference of conversion between the catalysts was observed indicating that well dispersed iron oxide species are active species for this reaction. Nevertheless, the obtained activity remains lower than catalysts containing iron cationic species at the exchange sites.
