Copper-exchanged sodium Y zeolites have been studied by using 129Xe 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 129Xe NMR measurements on Cu-Y and Cu-Rho zeolites.
通过使用129Xe核磁共振（NMR）光谱对铜交换的钠Y沸石进行了研究。已确定了不同交换水平（λ = 15%、35%、58%）、不同水合程度以及不同氧化还原处理阶段的不同样品中铜在沸石中的氧化态和位置。通过对Cu-Y和Cu-Rho沸石进行电子自旋共振（ESR）和129Xe NMR测量相结合，获得了有关Xe-Cu+或Xe-Cu2+相互作用性质的信息。
