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.
