“…In order to reduce the emissions of CO 2 , several measures are being adopted by many countries. In this context, Carbon Capture and Utilization (CCU) is one of several approaches that have been proposed to decrease emissions [1][2][3]. This work is focused on the utilization of CO 2 to transform it into dimethyl ether (DME) through a reaction with hydrogen obtained from renewable sources; DME, due to its chemical-physical properties, can be used as fuel in substitution of LPG (Liquified Petroleum Gas), maintaining the same transport and storage technologies.…”

Mesostructured γ-Al2O3-Based Bifunctional Catalysts for Direct Synthesis of Dimethyl Ether from CO2

In this work, we propose two bifunctional nanocomposite catalysts based on acidic mesostructured γ-Al2O3 and a Cu/ZnO/ZrO2 redox phase. γ-Al2O3 was synthesized by an Evaporation-Induced Self-Assembly (EISA) method using two different templating agents (block copolymers Pluronic P123 and F127) and subsequently functionalized with the redox phase using an impregnation method modified with a self-combustion reaction. These nanocomposite catalysts and their corresponding mesostructured supports were characterized in terms of structural, textural, and morphological features as well as their acidic properties. The bifunctional catalysts were tested for the CO2-to-DME process, and their performances were compared with a physical mixture consisting of the most promising support as a dehydration catalyst together with the most common Cu-based commercial redox catalyst (CZA). The results highlight that the most appropriate Pluronic for the synthesis of γ-Al2O3 is P123; the use of this templating agent allows us to obtain a mesostructure with a smaller pore size and a higher number of acid sites. Furthermore, the corresponding composite catalyst shows a better dispersion of the redox phase and, consequently, a higher CO2 conversion. However, the incorporation of the redox phase into the porous structure of the acidic support (chemical mixing), favoring an intimate contact between the two phases, has detrimental effects on the dehydration performances due to the coverage of the acid sites with the redox nanophase. On the other hand, the strategy involving the physical mixing of the two phases, distinctly preserving the two catalytic functions, assures better performances.

“…By harnessing CO 2 as a resource rather than treating it solely as a waste product, we can drive the development of innovative technologies and catalytic systems that enable its conversion to high-value products. Embracing CCU not only presents an opportunity to reduce CO 2 emissions but also offers a sustainable pathway toward a circular carbon economy, where CO 2 is effectively recycled and utilized, thereby contributing to climate change mitigation. , One viable approach for utilizing carbon dioxide is through its hydrogenation into methane, which serves as a substitute or synthetic natural gas. − The process involved in converting CO 2 and hydrogen into methane is commonly referred to as CO 2 methanation, which can be regarded as a power-to-gas conversion. − …”

This study explores the employment of CO 2 methanation for carbon dioxide utilization and global warming mitigation. For the first time, in this work, we combine the interesting properties of the WO 3 –ZrO 2 support and the benefits of Sr to improve the performance of Ni-based catalysts in this reaction. Sr loading on 5Ni/W–Zr samples is increased to 3 wt %, resulting in improved surface basicity through strong basic site formation. After 300 min, the 5Ni + 3Sr/W–Zr catalyst exhibits high activity and stability, achieving 90% CO 2 conversion and 82% CH 4 yield compared to 62 and 57% on 5Ni/W–Zr. Limited sintering and absence of carbon deposits are confirmed by temperature-programmed oxidation, XRD, Raman, and TEM analyses at 350 °C for 300 min. Sr promotion creates additional CO 2 adsorption and conversion sites, enhancing the catalytic performance.
