N2 - Zeolites are widely used in industry as molecular sieves, ion exchangers and catalysts. According to recent studies mesoporosity is beneficial to the rational design of catalysts with controlled product selectivity and the improved catalyst lifetime due to the efficient mass- transport properties. To tailor structures and morphology of zeolite catalysts for specific reactions, it is necessary to understand the effects of various modifications (either during synthesis or post- synthetic treatments) on physico- chemical properties of the target material. Nuclear magnetic resonance (NMR) has proven to be a reliable method for studying zeolite structure, surface acidity and dynamics of adsorbed molecules. This Chapter reviews recent NMR studies of zeolites with hierarchical porosity mainly focusing on, structural studies by 27Al and 29Si NMR spectroscopy, 2D T1- T2 correlation and T2- T2 exchange experiments and NMR cryoporometry.
