Abstract
<p>The method of potentiometric titration and corresponding determination of pK<sub>a</sub> of acid sites by the Gran method was applied for hierarchical zeolite materials. For hierarchical Al-, Ga- and B-silicate zeolites of MOR, BEA, MFI and MTW structural types with the morphology of aggregated nanosheets, nanorods or close to spherical nanoparticles, the distribution of acid sites by strength was determined. The dependence of the acidity spectrum (strength of acid sites) on the type of zeolite structure and the nature of an isomorphously substituted cation, on the one hand, and on the morphology of zeolite nanocrystals, on the other hand, was demonstrated.</p>
