Summary: The promotional effect of mixed ceria-zirconia oxides (CZO) on the Mo/HZSM-5 catalyst for methane dehydroaromatization (MDA) reaction was studied. The surface and structural properties of the synthesized catalyst were thoroughly characterized, and the correlation between catalytic properties and MDA reaction performance was discussed. The impregnation of CZO solid solution on Mo/HZSM-5 improved the catalytic performance and benzene production rate, while reducing coke formation. The redox properties of CZO-deposited Mo/HZSM-5, acting as a selective oxygen supplier and performing hydrogen combustion, were identified as the main reasons for the enhanced catalytic activity.
