Abstract

High resolution 27Al NMR spectroscopy has been used to study the dealumination of the A-type zeolite ZK4. The aluminum removed from the lattice during calcination undergoes reversible changes in coordination when treated in acidic and basic media. 2 5 Si NMR spectroscopy reveals that the changes are confined to the detrital aluminum species and do not affect the zeolite framework. Thermogravimetric analysis data combined with compositional data available from 29Si NMR spectra have been used to probe the state of charge of the detrital aluminum species and the nature of defects present in the lattice.
