英文摘要Multinuclear solid state NMR was employed to study the silicon-substituted molecular sieve Si-VPI-5. Si-29 and Al-27 NMR suggest that Si can be incorporated into the framework of VPI-5 and the substitution of two silicon atoms for an aluminium atom plus a phosphorus atom is predominant. such substitution is limited in a certain domain of the crystal and "silcon rich" regions are thus generated. H-1 MAS spectra reveal that a small amount of silicon atoms substitute phosphorus only and SiOHAl groups are formed, which provides the acidic source for the molecular sieves. Si-VPI-5 prepared with silica gel as the silicon source exhibits a higher content of SiOHAl groups than that prepared with (EtO)(4)Si.
