Anotace	High-silica zeolites with crystalline aluminosilicate frame- works balance the charge of strongly acidic protons during the processing of oil, in petrochemistry, and increasingly in numerous organic syntheses. The transformation of hydro- carbons is controlled by the concentration and strength of the acid sites and the dimensions and architecture of the inner pores. Zeolite micropores, which have a diameter similar to organic molecules, govern the shape selectivity of the reaction in the inner space, but also result in slow transport of reactants and products, thus limiting the reaction rate. [1] Several approaches have been developed to enhance the mass transport by using zeolite nanosheets and nanocrystals, [2–4] or zeolites that contain both micro- and mesopores. The latter hierarchical zeolites were prepared by confined crystal growth, [5,6] by using polymers as mesoporogens, [7] or through post-synthesis desilication or dealumination processes.
