Herein, FeOx-supported ZSM-5 exhibited excellent catalytic performance in the aromatization of methanol, similar to ZnOx-supported ZSM-5 but with much longer life time. Coating of FeOx/ZSM-5 catalyst with a SiO2 shell is effective to suppress the isomerization of xylene and hydrogen transfer from propylene to propane on the external surface. As a result, FeOx/ZSM-5@SiO2 exhibited gross yield of C2–C3 olefins and para-xylene (carbon base) far higher than that of HZSM-5, ZnOx/ZSM-5, and ZnOx/ZSM-5@SiO2.
