Unusually high and stable catalytic activity of Cu/H-ZSM-5 in methane oxidation: correlation with coordination state of Cu(II) cations

Catalytic oxidation of CH{sub 4} with O{sub 2} using Cu(II)-containing H-ZSM-5 was studied. An ESR study was carried out on copper ion distribution and coordination in zeolite. It was shown that H-ZSM-5 zeolite containing isolated Cu(II) cations in coordinatively unsaturated environments demonstrate...

Description
Summary:Catalytic oxidation of CH{sub 4} with O{sub 2} using Cu(II)-containing H-ZSM-5 was studied. An ESR study was carried out on copper ion distribution and coordination in zeolite. It was shown that H-ZSM-5 zeolite containing isolated Cu(II) cations in coordinatively unsaturated environments demonstrated high and steady-state activity in the redox-type catalytic reaction of methane oxidation.
