[Display omitted] ▶ Influence of cations in the zeolite on NOx reduction by NH3 over Cu/ZSM-5 studied. ▶ Cu/0.6NaZSM-5 is more active for NOx reduction with NH3 compared with Cu/HZSM-5. ▶ Na+ cations tailor the Cu+/Cu2+ active species. ▶ Na+ cation also enhances intermediate nitrogen oxides formatio...
