Incorporation of Copper in SiBEA Zeolite as Isolated Lattice Mononuclear Cu(II) Species and its Role in Selective Catalytic Reduction of NO by Ethanol

The Cu(x)SiBEA zeolites prepared by a two-step postsynthesis method are active in selective catalytic reduction of NO by ethanol and their catalytic activity is related to the presence of mononuclear Cu(II) species. Zeolite with isolated lattice mononuclear Cu(II) species is active in this reaction with selectivity toward dinitrogen close to 70-90%.
