The results obtained in this work demonstrate the possibility to integrate the two functionalities of methanol-synthesis and methanol-dehydration in hybrid catalysts for the direct production of DME from CO2 hydrogenation. Apart from the need of optimal experimental parameters, the crucial issue for preparing a high-active multi-site system is optimizing the formulation and interaction of metallic, oxide(s) and acidic components, so to realize a punctual mix of surface sites necessary for the primary formation of methanol, followed by its dehydration to DME on acid sites of the zeolite. Overall, in the perspective to develop an active and stable multi-site catalyst for the production of DME from CO2, the concurrence of textural, structural and surface factors must be adequately balanced.
