Abstract
The oxidation state of copper ions in Cu-ZSM-5 zeolites prepared by co nventional and solid state ion-exchange procedures was studied by ESR spectroscopy. The coordination of Cu2+ ions are influenced by the pret reatment conditions (oxidation, reduction) and by NO adsorption. (C) 1 997 Elsevier Science B.V.
