| Abstract: | The kinetids of NO decomposition to N2 over Cu-ion exchanged ZSM-5 with different Si/Al ratios and the change of the specific activity per copper site as a function of the Cu/Al ratio suggest that the copper species formed at a Cu/Al ratio of 0.5 or higher and probably containing extra-lattice oxygen have higher turnover frequency in the reaction. |
