Characterization of hydrotreated Cu-ZSM-5 catalyst for the selective catalytic reduction of no by n-decane
The steam treatment of Cu-ZSM-5 prepared by solid ion exchange involves an important decrease of the NO conversion. Characterization of the solids by NO-TPD, H-2-TPR, Al-27 MAS NMR shows that the catalyst deactivation is mainly due to change in copper species rather than the collapse of the zeolite framework.
