Comparison of Morphology and Physicochemical Properties of Embryonic and Nanosized ZSM-5 Zeolites and Their Use in the Dealkylation Reaction of Aromatic Hydrocarbons (a Review)

This review presents the analysis of the characteristic features of the structure, synthesis methods, and physicochemical properties of embryos that form the basis of ZSM-5 zeolites. Various physicochemical characteristics of the embryos and nanocrystals of ZSM-5 (X-ray diffraction, textural characteristics, morphology, infrared and nuclear magnetic resonance spectroscopy) are discussed and compared, and their similarities and differences are analyzed.
