Abstract

1H MAS NMR spectra of perfluorotributylamine adsorbed on HZSM-5 zeolites loaded with or without molybdenum show that it is a promising probe molecule for distinguishing the internal and external acidic sites in zeolites as well as for determining the position of silanols and some non-framework Al species.
