“…According to Ateka et al, the production of DME is maximized at temperatures between 250 and 275 °C. 82 As the process of converting CO 2 into DME necessitates two successive steps (the conversion of CO 2 into methanol followed by its dehydration into DME), the catalysts used in this process require two different kinds of active sites (bifunctional catalysts) (Table 2): a metal active site for methanol synthesis and an acid active site for the dehydration process. 87 Cu/ZnO/Al 2 O 3 is an example of a bifunctional catalyst that can convert CO 2 into DME.…”

Carbon capture is an emerging technology that is often mentioned as a potential solution to the global warming crisis. However, most of the captured carbon is now treated as waste, discarded, and not used in any meaningful way. On the other hand, from a sustainable development point of view, CO 2 valorization could be a very appealing approach that offers an economic potential when this compound is recycled into valuable chemical products. In this regard, this state-of-the-art review encompasses a wide range of different processes to achieve the conversion of CO 2 into a large variety of products. It does not focus solely on a specific reaction or method, but rather brings different aspects together to provide a far more complete portrait of this emerging subject. Several methods and approaches are discussed, namely thermochemical, electrochemical, photochemical, photoelectrochemical, biochemical, and plasma-assisted conversion. The current state of CO 2 valorization, as well as emerging alternatives and stimulating prospects, was examined, while bearing in mind the realities that limit the application of such technologies. Special emphasis was placed on the optimization of reaction conditions and the development of materials that ensure the best possible production of valuable and environmentally friendly compounds from CO 2 . This review also highlights the challenges related to the application of CO 2 valorization at an industrial scale, which are also important in directing further research in this domain and assessing the prospects of these technologies. Due to the growing number of published papers on the subject, and the limited number of papers offering such a large perspective, we thus believe that this review will be a valuable addition to guide all researchers involved in the field of CO 2 valorization, but also for industrial and political leaders interested in investing in and developing these promising new technologies.

“…10) is another attractive reaction, that proceeds from CO 2 to DME via the formation of methanol followed by its dehydration into dimethyl ether. This reaction is seeing a resurgence in interest given that DME is a viable alternative to petrochemical hydrocarbons as a fuel or as a precursor for other complex compounds [175][176][177][178]. Furthermore, the formation of olefins, aromatics and gasoline can be formed from methanol that is ultimately synthesized from CO 2 hydrogenation [176].…”

“…On the other hand, the separation of the methanol synthesis and dehydration reactions, which take place in the core and the shell, respectively, favors the catalytic performance and limits water presence in the metallic core. Therefore, methanol is forced to pass through acid sites to diffuse out of the catalyst, enhancing the dehydration reaction that takes place at acid sites [144]. CZA catalysts hybridized with zeolites can also be tuned to rare earth metals, as they are suggested to act as promoters to enhance metal dispersion and as thermal stabilizer [145,146].…”

Silica-Related Catalysts for CO2 Transformation into Methanol and Dimethyl Ether

The climate situation that the planet is experiencing, mainly due to the emission of greenhouse gases, poses great challenges to mitigate it. Since CO2 is the most abundant greenhouse gas, it is essential to reduce its emissions or, failing that, to use it to obtain chemicals of industrial interest. In recent years, much research have focused on the use of CO2 to obtain methanol, which is a raw material for the synthesis of several important chemicals, and dimethyl ether, which is advertised as the cleanest and highest efficiency diesel substitute fuel. Given that the bibliography on these catalytic reactions is already beginning to be extensive, and due to the great variety of catalysts studied by the different research groups, this review aims to expose the most important catalytic characteristics to take into account in the design of silica-based catalysts for the conversion of carbon dioxide to methanol and dimethyl ether.
