| Abstract: | The catalytic selective reduction of NO over metal‐exchanged (ZnII, AgI) natural zeolites (mordenite and clinoptilolite) from Cuba using NH3 as a reducing agent in the presence of excess oxygen was studied. Both transition metals slightly improve the catalytic performance for the NO reduction. ZnII‐exchanged zeolites exhibit a moderate catalytic activity, with conversions of NO of ≈58 % and high selectivity to N2 at high temperatures. |
