Abstract
Cadmium ions have been introduced in extra-framework positions of zeolite Y by vapour deposition of cadmium metal in HY and subsequent redox reaction. The samples so-obtained have been investigated with carbon monoxide and xenon adsorption as well as with 129 Xe NMR spectroscopy. Unusual distributions of the Cd 2+ ions with preference for the low oxygen-coordinated S III sites in the supercages were detected. A subsequent rehydration/dehydration cycle leaves the sample with a Cd 2+ distribution similar to zeolites obtained by conventional aqueous ion exchange.Keywords
