eng	SELECTIVE OXIDATION OF METHANE TO METHANOL OVER BINUCLEAR SPECIES IN ZEOLITES	Zeolites represent the largest group of heterogeneous catalysts apply for fl uid catalytic cracking, selective catalytic reduction of hydrocarbons, and for NOx abatement. Recently, it was shown that iron-exchanged zeolites (*BEA and ZSM-5) eff ectively stabilized active oxygen from N2O, which can be further used for oxidation of methane to methanol[1]. Our previous results supported by DFT calculation revealthat binuclear Fe species in ferrierite (FER) are responsible for easier splitting of N2O and stabilization of active oxygen (Fig. 1)[2, 3]. The aim of this work was targeted at preparation of the binuclear Me (Me = Co, Ni, Mn) centers in FER and FTIR analysis of their redox properties in selective oxidation of CH4 originating from N2O.	catalyst; transition metal; methanol; zeolite; binuclear species
