Selective catalytic reduction of N2O with CH4 on Ni-MOR: A comparison with Co-MOR and Fe-MOR catalysts.

Highlights: [•] Ni-MOR, Co-MOR and Fe-MOR are active for SCR of N2O with CH4 in the presence of O2. [•] Despite relative H+ and Na+ amount, the activity order is Fe-MOR>Ni-MOR>Co-MOR. [•] The CO2 selectivity is 100% on Ni-MOR and lower on Fe-MOR and Co-MOR. [•] Ni-MOR are promising catalysts for the simultaneous SCR of N2O and NO x using CH4. [•] On all catalysts FTIR showed isolated tmi with at least two coordinative vacancies. [Copyright &y& Elsevier]
