Remarkable catalytic properties of hierarchical zeolite-Beta in epoxide rearrangement reactions
Popis výsledku v původním jazyce
Hierarchical Beta zeolites with enhanced accessibility obtained by crystallization of silanized zeolitic seeds were synthesized and investigated as catalysts for epoxide rearrangement reactions. On the other hand, hybrid zeolitic?mesoporous materials prepared from Beta protozeolitic units, and later assembled around cetyltrimethyl ammonium bromide (CTAB), were also synthesized for comparison purposes. Textural and structural properties were studied by N2 and Ar adsorption isotherms, X-ray diffraction (XRD) and transmission electron microscopy (TEM). The coordination and stability of the Al atoms were investigated by 27Al MAS NMR. The acidic properties were analyzed by NH3 temperature programme desorption (TPD), and by FTIR probe pyridine adsorption?desorption to get insights on their acidic features and population of Br?nsted and Lewis acidity. These zeolitic type materials featured additional porosity and enhanced textural properties compared with the conventional Beta zeolite and Al-
