![عکس صفحه اول مقاله: Synthesis, characterization and catalytic activity of a novel mesoporous ZSM-5 zeolite Synthesis, characterization and catalytic activity of a novel mesoporous ZSM-5 zeolite](/preview/png/1489200.png)
A novel mesoporous ZSM-5 zeolite was hydrothermally synthesized using glucose as a template. Characterizations by XRD, TEM and nitrogen isotherms indicated that ZSM-5 possessed worm-like mesoporous. 27Al-MAS-NMR and NH3-TPD showed that the mesoporous ZSM-5 preserved tetrahedral coordination aluminum and stronger acidity than conventional mesoporous material. As-prepared mesoporous ZSM-5 was successfully used in alkylation reaction of phenol with tert-butanol and exhibited significantly high phenol conversion and 2,4-DTBP selectivity. In addition, the hydrothermal stability was also studied by boiling in water for 7 days and displayed good results.
