微波法高度分散CuCl2-β沸石上CO吸附的IR光谱研究

CO adsorption on β zeolite with highly dispersed CuCl 2·2H 2O was studied by IR spectroscopy. The results of XRD and 29 Si NMR indicate that CuCl 2·2H 2O is highly dispersed into β zeolite channel as a monolayer. The IR spectra of adsorbed CO on 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 CuCl 2·2H 2O.
