Реферат: It is suggested that the abnormal methane IR frequency shift observed in ZnZSM-5 zeolites is caused by adsorptive interaction of CH4 with particularly strong Zn2+ Lewis sites. Various molecular structures of zinc ion species in high-silica zeolites are discussed, and it is concluded that increased Lewis acidity of a site is associated with decreased structural stability. It is shown that Zn2+ in zeolite cationic position with distantly placed A1 ions can produce observed shift of vibrational frequencies for adsorbed methane molecule.
