Abstract
Siting of metal ions (Zn2+, Co2+, Cu+) in the cationic sites of (A1)MCM-41 matrix has been investigated employing UV-VIS-NIR DR spectroscopy and UV-VIS emission spectroscopy. Four types of cationic sites were identified in dehydrated (Al)MCM-41. Divalent (Zn2+or Co2+) ions are accommodated only in two sites. Cu+ ions in reduced, Cu2+ ion exchanged (Al)MCM-41, occupy four types of cationic sites. Two sites are accessible for divalent cations, other two only for monovalent cations. Distribution of cations among sites depends on the metal ion loading in molecular sieve.
