Abstract

A new zeolite (IM5) whose structure has not been resolved yet is tested for the selective catalytic reduction (SCR) of NO with C3H8 and characterized by in situ X-ray photoelectron spectroscopy. The catalytic behavior of copper exchanged IM5 zeolite is compared with that of copper exchanged ZSM5 zeolites. The influence of the partial pressure of oxygen, reaction temperature and exchange level of the metal in the catalyst is similar to that observed with copper exchanged ZSM5 zeolite, but Cu–IM5 is a more active and hydrothermically more stable catalyst than Cu–ZSM5.
