“…Electrochemical CO 2 reduction reaction is only possible at applied potentials of at least 1.0 V, whereas the plasma conversion of CO 2 results in O 2− fluxes at lower applied voltages. A key consideration when utilizing a membrane in plasma reactors is the chemical stability of the membrane used, which is reported to be the case for the solid oxide membranes used by Chen et al [46] and Pandiyan et al [51] 2.3 | Product removal in the liquid phase Products can also be removed in the liquid phase, either by (1) absorption in a liquid medium or by (2) condensation of products (see Figure 3).…”

This short review focuses on in situ product removal as a method to improve the energy efficiency and product yield of plasma‐based conversions. After recapping the advantages of in situ separations in thermal‐catalytic processes, different strategies for in situ product removal for plasma‐based conversions are discussed. Advantages and challenges are discussed regarding four strategies, that is, absorption and adsorption using solids, use of sacrificial reactants, separation with ceramic dense membranes, and product removal in the liquid phase.

“…Solar radiation also enhanced the CO 2 conversion due to interactions between solar photons and the excited plasmatic species, although the mechanism of such interaction is still unclear. Adding an electrolysis reactor after the plasma reactor was also envisioned, helping to separate the O 2− ions generated in plasma-assisted conversion from the generated CO. 357 The electrolysis reactor also helped to convert unreacted CO 2 into CO by electroreduction. Devid et al included a metallic mesh into their plasma reactor, which acted as a catalyst for oxygen recombination and reduced the recombination reaction of CO and O into CO 2 , increasing the CO 2 conversion by a factor of 1.2−1.8.…”

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.

“…Combinations of plasma and SOEC, i.e., the technology of MOXIE, which decomposes and electrolyzes CO 2 and separates out the O 2 product, 14,69,82 could also offer an intriguing prospect for the production of highly purified O 2 . Pandiyan et al 85 recently interrogated the electrolysis of a CO 2 MW-plasma-exhaust mixture consisting of CO, O 2 , and CO 2 . The authors showed that O 2 separation, in particular, can be achieved exclusively at low overpotentials (i.e., <0.75 V) and reduced temperatures (i.e., $650 C)-conditions where CO oxidation and CO 2 electrolysis (i.e., dissociation of CO 2 ) are not active.…”
