Designing materials for catalytic applications – case study of MFI- type zeolites

Zeolites are one of the most widely used solid heterogeneous catalysts due to their unique properties. Herein, a series of nanosized ZSM-5 samples (MFI framework type-material) was synthesized at 170, 150, 120, and 100 °C. Experimental data show that the decrease of crystallization temperature leads to significant changes in zeolite properties. Crystals synthesized at 100 °C exhibit many framework defects with lower acid-site density, strength, and a larger external surface area. The prepared materials have been tested as catalysts in DME synthesis and MTO reaction.
