IR Studies of CO Adsorption on β-Zeolite with Highly Dispersed CuCl2·2H2O Treated by Microwave

Abstract

Abstract: COadsorption on β-zeolite with highly dispersed CuCl₂·2H₂Owas studied by IRspectroscopy. The results of XRDand ²⁹Si NMRindicate that CuCl₂·2H₂Ois highly dispersed into β-zeolite channel as a monolayer. The IRspectra of adsorbed COon the zeolites demonstrate that two distinct types of adsorption sites exist in the zeolites, i.e., cation and non cation exchange sites. Two simultaneous processes, solid phase ion exchange and molecular diffusion, are involved in the dispersion of CuCl₂·2H₂O.

Key words: CuCl₂-&beta, zeolite, Microwave, CO adsorption, IR spectroscopy
