摘要：

Copper-exchanged sodium Y zeolites have been studied by using Xe-129 nuclear magnetic resonance (NMR) spectroscopy. The oxidation state as well as the location of copper in the zeolite have been determined for different samples at various levels of exchange (lambda = 15, 35, 58%) and hydration, and at different stages of redox treatment. Information about the nature of Xe-Cu+ or Xe-Cu2+ interactions has been obtained by a combination of electron spin resonance (ESR) and Xe-129 NMR measurements on Cu-Y and Cu-Rho zeolites.
