Nano ZSM-5 type ferrisilicates as novel catalysts for ethylbenzene dehydrogenation in the presence of N2O

► Several types of nanosized ZSM-5 type ferrisilicates were prepared by hydrothermal synthesis. ► Characterized using BET measurements, XRD, TEM, SEM-EDS and ICP techniques. ► Catalysts for selective ethylbenzene dehydrogenation to styrene. ► Potassium in the precursors, SiO2/Fe2O3 ratio and N2O play an important role in the reaction. ► K-FZ30 showed high yield of styrene.
