摘要：

Al, Ga and B silicate hierarchical zeolites of structural types MOR, BEA, MFI and MTW with morphology of nanorods, nanolayers or nanoparticles, due to the presence of optimal strength of Brønsted acid centers are active and highly selective catalysts for indanol dehydration in mild conditions (yield of the target product up to 99%). Ga and B silicate hierarchical zeolites with low and medium acidity show moderate yields in Beckman rearrangement of oximes. Hierarchical aluminosilicate zeolites of structural types MOR, BEA and MFI of different morphology show high activity in the process of n-hexane cracking, which allows us to consider them as promising catalysts for this reaction. Formation of the basic centers in zeolite composites with different nature and structure allows obtaining effective catalysts for the cycloaddition reactions under carbon dioxide pressure. © 2023, King Abdulaziz City for Science and Technology.
