“…The cross sections of a number of processes like elastic scattering, ionisation, momentum transfer, and double ionisation have been presented employing a variety of techniques: electron-ionisation mass spectrometry [23], photoionisation mass spectrometry [24], collisions with positrons [25], and coincidence techniques [26,27]. The TDCS of electron-CO 2 collisions has received relatively little experimental and theoretical attention despite all this work due to the molecule's complexity [28][29][30][31][32][33]. Hussey and Murray conducted the first experimental study of (e, 2e ) [34] on CO 2 molecule.…”

Theoretical investigations of electron-impact ionisation for carbon dioxide (CO2 ) in low to intermediateenergy ranges are presented. In addition to the energy range, we have estimated TDCSin coplanar and perpendicular plane geometry. We have calculated the TDCS for electron impactusing the modified distorted wave formalism up to the second order. Post-collision interaction (PCI)effects have also been introduced to describe the collision dynamics accurately.There is a good correlation between the DWBA results and the experimental results in terms offorward and backward scattering regions.

Dielectric barrier discharge (DBD) plasma is a potential tool in the field of in situ CO2 conversion with the low‐pressure environment of Mars. CO is an important intermediate product in the conversion process of CO2. Understanding the pathways and dynamics that govern the generation of CO in CO2 plasmas establishes the foundation for effective regulation. In this work, parallel‐plate DBD structure was employed in our experiment and one‐dimensional fluid simulation model. The findings indicate that CO primarily originates at the boundary of the cathode potential fall region, and it subsequently migrates toward the surface of instantaneous cathode where it accumulates. The thickness of CO‐enriched region is approximately 0.8 mm. During this process, CO migration speed reaches about 2000 m/s. It is worth noting that surface reactions at the instantaneous cathode and anode surfaces contribute only 0.24% to CO generation, in contrast to the predominant influence of impact dissociation reaction between CO2 and electrons (e + CO2 → 2e + CO + O+) at 53.21%, and two‐body decomposition reaction between O+ and CO2 (O+ + CO2 → O +2 + CO) at 35.88%. Finally, the primary factors influencing the migration of CO from production sites to enrichment regions are determined to be particle collisions and momentum exchange between ions and CO, followed by electro‐hydro dynamics force, while dielectrophoresis forces have minimal effect.
