  Abstract

In this study, we investigated the activity of Pd and Pt supported on acidic Fe-ZSM5 supports for selective catalytic oxidation of ammonia (NH3-SCO). Among the catalysts, Pt/Fe-ZSM5 catalyst exhibited superior NH3-SCO activity to Pd/Fe-ZSM5 catalyst. We also tested Pt/Fe-ZSM5 catalysts with different Fe loading using ion-exchange method to prepare Fe-ZSM5 supports, which resulted in the increased catalytic performance with smaller Fe content: NH3 was oxidized completely at low temperature (250 ℃). The physicochemical properties of Fe-ZSM5 were investigated to figure out the relationship between the characteristics of the catalysts and the catalytic activity on NH3-SCO by Inductively coupled plasma-atomic emissions spectrometer (ICP-AES), N2 sorption, X-ray diffraction (XRD), temperature programmed desorption of NH3 (NH3-TPD) technique.
