Nitric oxide adsorption on copper exchanged Y zeolites is investigate&by means of ESR and IR techniques. It is shown that NO disproportionation is copper cuncentration dependent as 1$1 as NO adsorption which occurs qn CO-.: reduced samples on Cuz+ \_ Ions for low exchanged Y zeolites and on Cu+ ions
The ESR technique has been used to study the localization of copper@) ions in the zeoijte framework. In the enti@y hydrated samples the copper(H) ion is in the form of an hexazquo complex localized in the centre of the supercage. Dehydration produces the migration qf the ion toward the sodalite cage
