Abstract

23Na double-rotation NMR (DOR) spectroscopy provides details on site-specific adsorption of various molecular guests within the nanometer-dimension void spaces of sodium zeolite-Y. Anchoring of hexacarbonyl metal(0) precursors, as well as their molecular metal oxide photooxidation products, to specific extraframework sodium cation sites, is readily detected by 23Na DOR. Loading-dependent chemical shifts and line-shape alterations yield useful information on the structure, bonding and organization of the guests within the zeolite host lattice.
