The hierarchical-structured Zn/Mo-HZSM-5 catalyst was synthesized by two-step crystallization and impregnation method, and characterized by XRD, HRTEM and N2 adsorption-desorption. The results indicates that the obtained catalyst has a large specific surface area and pore volume. The catalyst exhibits good activity and stability in DME aromatization. The selectivity of aromatics reaches 84.5% at 420°C. When the reaction time reaches 160h, the total aromatics selectivity remain at 71.2%. Keywords-hierarchical-structured; Zn/Mo-HZSM-5; DME; aromatization.
