Description
| - Interakce CO s mimomřížkovými Li+ ionty koordinovanými v ZSM-5 a FER zeolitech s různým složením byla zkoumána a vztah mezi Li+ koordinací, stabilitou a frekvencí vibrace karbonylových komplexů byl diskutován spolu s teoretickým výzkumy stability a vibrační dynamiky. Rozdíly ve spektrech byly zkoumány vzhledem k (i) různému Si/Al, (ii) rozdílné struktuře zeolitu, (iii) teplotě , (iv) typu ko-kationtu. Získané korelace mezi koordinací a frekvencí vibrací karbonylových komplexů byly extrapolovány do mesoporézních materiálů Li-(Al) MCM-41. Spektrální pásy byly přiřazeny k COLi+ komplexům na vrcholu 5- a 6-člených kruhů na povrchu stěn kanálů. (cs)
- The interaction of CO with extraframework Li+ ions coordinated in ZSM-5 and FER zeolites with different compositions is investigated by FTIR spectroscopy, and the correlation between Li+ coordination, stability of CO adsorption complexes, and nu(CO) frequencies is discussed in terms of the theoretical investigation of the stability and vibrational dynamics of CO adsorption complexes. Differences in IR spectra of adsorbed CO due to the following effects were considered: (i) various Si/Al ratios, ( ii) differences in zeolite topology, ( iii) temperature, and ( iv) the effect of a co-cation on relative stability and metal cation site preferences. The correlation between Li+ coordination and nu(CO) frequencies of CO adsorption complexes discussed for Li zeolites is extrapolated to mesoporous Li-(Al) MCM-41 materials. The features in the IR spectra of CO/Li-(Al)MCM- 41 are assigned to CO adsorption complexes formed on top of five- and six-membered rings on the surface of a channel wall. The spectra of CO/L
