{"title":"Generation and migration of CO in CO2 DBD glow plasma under Martian pressure","authors":"Qiang Fu, Zifan Ye, Honglin Guo, Zhixin Duan, Jialun Luo, Zhengshi Chang","doi":"10.1002/ppap.202400085","DOIUrl":"https://doi.org/10.1002/ppap.202400085","url":null,"abstract":"Dielectric barrier discharge (DBD) plasma is a potential tool in the field of in situ CO<jats:sub>2</jats:sub> conversion with the low‐pressure environment of Mars. CO is an important intermediate product in the conversion process of CO<jats:sub>2</jats:sub>. Understanding the pathways and dynamics that govern the generation of CO in CO<jats:sub>2</jats:sub> 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 CO<jats:sub>2</jats:sub> and electrons (e + CO<jats:sub>2</jats:sub> → 2e + CO + O<jats:sup>+</jats:sup>) at 53.21%, and two‐body decomposition reaction between O<jats:sup>+</jats:sup> and CO<jats:sub>2</jats:sub> (O<jats:sup>+</jats:sup> + CO<jats:sub>2</jats:sub> → O<jats:sup> +</jats:sup><jats:sub>2</jats:sub> + 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.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"47 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, plasma interactions with liquids are more diverse. In this review, we look from the chemical point of view at the three fields of plasma–liquid interaction in which plasma is used to convert organic substrates. In wastewater treatment, plasma decomposes organic substances: the selectivity towards specific products is less crucial than process energy costs. In the conversion of organic liquids for sustainable energy purposes, the carbon and hydrogen selectivity to syngas are important, but these are still destructive reactions yielding small molecules. Finally, we provide a comprehensive plasma application list for synthetic organic chemistry and discuss their mechanisms and limitations.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"8 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emission spectra are dominated by dicarbon Swan bands and black body radiation from carbon nanoparticles. Both spectral features are utilized to estimate the gas temperature. In the center of the plasma, gas temperatures of up to 4300 K are reached with large gradients (500 Kmm<jats:sup>‐1</jats:sup>) in the radial direction.

The high‐resolution time diagnostics of ns pulse plasma interacting with micron‐sized droplets under high‐humidity conditions is challenging to achieve with existing experimental methods. This paper employs a global model to study the interaction between plasma and droplets, offering a detailed analysis of the plasma's transition from the gas phase to the liquid phase. It was discovered that in high‐humidity environments, hydrated ions become the predominant ion species. These acidic active substances in PAM droplets are the primary factors in the mist's ability to kill bacteria.

Importantly, this superhydrophobicity is achieved using OTMSD as fluorine‐free precursor with low reactivity to water.
