Operando FTIR study of Fe-MOR, Co-MOR, and Ni-MOR as catalysts for simultaneous abatement of NOx and N2O with CH4 in the presence of O2. An insight on reaction pathway
Co-, Fe- or Ni-exchanged Na-MOR (Si/Al=9.2) were prepared by ion-exchange method. The catalytic activity of
Fe-MOR catalyst for the simultaneous selective catalytic reduction of NOx and N2O with CH4 in the presence of
excess O2 (SCRsim) and for the related reactions (SCRN2O, SCRNO, N2O decomposition, N2O decomposition in the
presence of NO and CH4 combustion) was investigated and compared with that previously measured for Co-MOR
and Ni-MOR. The evolution of the surface species on Co-, Fe- or Ni-MOR (tmi-MOR) in the presence of flowing
