The alkalinity of the precursor gels tailored the formation of the mesoporous structure and the crystal size of the ZSM-5 zeolite. The most regular mesopores in the ZSM-5 crystals were formed under grinding synthesis of the precursor gel with a defined concentration of alkali cations (Na 2 O/SiO 2 = 0.113). The size of the mesopores in the …
