This study involves the design and synthesis of novel mesoporous silica supported ionic liquid based adsorbents for carbon dioxide capture. Utilization of MSILs delves into the efficiency and mechanisms of CO₂ adsorption, offering insights for sustainable carbon capture technologies in combating greenhouse gas emissions. 1-ethyl-3-methylimidazolium tetrafluoroborate, 1-ethyl-3-methylimidazolium ethyl sulfate and 1-ethyl-3-methylimidazolium methylsulfate ionic liquids were anchored on the surface of mesoporous silica which then led to highly efficient adsorbent material. Simple, efficient and cost saving methodology was performed to synthesize such highly efficient CO₂ adsorbent materials.

The process can be considered a typical example of transition metal extraction by an ionic liquid. Conductivity and chemical (FTIR) analyses indicate that Co²⁺ complexes with the IL. Three different models are evaluated, all different with respect to the actual Co²⁺ species that complexes with the IL, as well as the Co²⁺:IL stoichiometry. Based on simulations we identified CoCl₂ as the Co species that enters and complexes with the IL, in a Co²⁺:IL ratio of 1:2. The complexation reaction between the Co-species and the IL is an endothermic, entropy-driven reaction. The influence of the feed composition on Co²⁺ extraction is investigated, including the effect of the nature of the accompanying anion as well as the presence of a salting out cation agent. The higher Co²⁺ extraction from a NO₃⁻ medium is due to the stronger interaction between Co(NO₃)₂ and the IL, reflected by a higher equilibrium constant of Co(NO₃)₂ compared to CoCl₂. Differences in dehydration enthalpy between the ion species involved may contribute as well. Similar effects play a role when comparing uptake rates in solutions containing both Co²⁺ and Na⁺, with Co²⁺ extraction clearly preferred over that of Na⁺. Observed differences in Co²⁺ uptake in the presence of a salting-out agent (NaCl, KCl and NH₄Cl) can be explained in terms of the hydration energy of the salting out cation, the higher this hydration energy, the higher the Co²⁺ uptake by the IL.</p></div>","PeriodicalId":100794,"journal":{"name":"Journal of Ionic Liquids","volume":"4 1","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277242202400020X/pdfft?md5=2aac78af15813cd096703390c882fea3&pid=1-s2.0-S277242202400020X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140905699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can be used as alternatives to other cellulosic fibers that have higher environmental impacts. However, to use hemp fibers effectively, they need to be separated from the lignin in the hemp biomass. This process is called delignification, and it is usually done by using harsh chemicals that are harmful to the environment and human health. In this work, we used a new and green solvent, called deep eutectic solvent-like mixtures, to delignify hemp biomass. Deep eutectic solvent-like mixtures are made from choline chloride and lactic acid, which are cheap, safe, and biodegradable. We tested different combinations of temperature (80–160 °C), time (60–240 min.), and solvent amount (1:10–1:60) to find the best conditions for delignification. We measured the Kappa number, which indicates how much lignin is left in the fibers, and the efficiency of delignification, which indicates how much lignin is removed. The Kappa number of delignified hemp fibers ranged from 10.7 (144 °C, 204 min, 1:30) to 21.8 (160 °C, 150 min, 1:17). The results showed that the optimal conditions to obtain the smallest Kappa number representing 6.6 are the boundary conditions of 160 °C, 240 min, and a ratio of 1:60.
