Redox couples in the selective catalytic reduction of NOx with hydrocarbons over Co-ZSM-5 and Ni-ZSM-5 catalysts: an FT-IR study.
On the basis of IR spectroscopy studies it is concluded that the redox couples Co(2+)/Co(+) and Ni(2+)/Ni(+) operate in the selective catalytic reduction of nitrogen oxides with hydrocarbons over Co-ZSM-5 and Ni-ZSM-5.
