Summary
Theoretical and experimental investigations of intrinsic and enhanced Broensted acidity i) show no evidence for a significant effect on intrinsic acidity arising from neutralisation of some of the acid sites, ii) suggest a suitable scale for protic acidity using CO as a probe, iii) provide a fundamental functional linearity for the correlation of shift in hydroxyl frequency and changes in band intensity, iv) allow deconstruction of complex infrared spectra of zeolite OH region, and v) demonstrate the basis for generating Broensted sites of enhanced acidity by interaction of Lewis sites with proximate Broensted sites in zeolites.
