Abstract
Chemical state analysis of silver species in Ag+ exchanged zeolite A and Y catalysts were carried out by means of XAFS and UV-Vis spectroscopies. Order of thermal stability of silver cluster was Ag(50%)-Y > Ag(60%)-A > Ag(100%)-A, which was consistent with the previous 1H NMR study for stability of chemisorbed hydrogen species. The three shell model (Ag-O, Ag-Ag, and Ag-Al/Si) of silver cluster in zeolites was proposed. © 2009 IOP Publishing Ltd.
