Abstract: The synthesis of hierarchical zeolite ZSM-5 in proton form using glucose under microwave irradiation is reported for the first time. The obtained materials were studied by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N₂ sorption and thermal desorption of ammonia. The hierarchical zeolite ZSM-5 in proton form has predominantly contained weak acid sites; the mesopore volume and total pore volume were 0.5 cm³g^–1 and 0.58 cm³g^–1, respectively.

Keywords: hierarchical ZSM-5 zeolite, hydrothermal microwave synthesis, biotemplate, proton form, glucose, micro/mesopores, interparticle porosity.
