    This article presents the method of Selective Catalytic Reduction as an example of usage in nitrogen oxides decomposition to molecular nitrogen and oxygen. The review is mainly focused on the description of the catalytic properties of CoZSM-5 in selective catalytic reduction (CH4-SCR) of nitrogen oxides. Due to EPR and UV-VIS researches speciation of cobalt ion in ZSM-5 matrix was described and TOF analyses helped to characterize the most active catalytic center. Furthermore, the mechanism of the NOx reduction and the formation of Co dinitrosyl complexes, as an important intermediate in SCR reaction, was presented.
