The application of CuO and MgO nanoparticles in CO2 capture was evaluated experimentally using 5% CO2 in nitrogen via physisorption and chemisorption instrumentation. The structural and surface micrograph of the CuO and MgO nanoparticles were characterized by XRD and TEM, respectively. After CO2 capture by the CuO nanoparticles, the amounts of oxide, hydroxide, and carbonate phases in the adsorbents were determined by XPS measurements. No hydroxide phase was detected in the MgO nanoparticles because of the efficient transformation of MgO into MgCO3. Monolayer adsorptions of CO2 were shown to occur in the MgO nanoparticles with a total chemisorption of 5.0 mmol/g. After the fifth cycle, only 3% reduction of the CO2 chemisorption was reported because of some agglomeration by sintering during desorption.

Ionic liquids (ILs) are used in various fields of chemistry. One of them is CO2 capture, a process that is quite well described. The solubility of CO2 in ILs can be used as a model to investigate gas absorption processes. The aim is to find the relationships between the solubility of CO2 and other variables—physicochemical properties and parameters related to greenness. In this study, 12 variables are used to describe a dataset consisting of 26 ILs and 16 molecular solvents. We used a cluster analysis, a principal component analysis, and a K-means hierarchical clustering to find the patterns in the dataset and the discriminators between the clusters of compounds. The results showed that ILs and molecular solvents form two well-separated groups, and the variables were well separated into greenness-related and physicochemical properties. Such patterns suggest that the modeling of greenness properties and of the solubility of CO2 on physicochemical properties can be difficult.

This study investigates the removal efficiency of carbon dioxide by aqueous absorbents containing monoethanolamine (MEA), piperazine(PZ), diethylenetriamine(DETA) and ionic liquids in a rotating packed bed. The performance of an absorbent was assessed in terms of an overall volumetric mass transfer coefficient and regeneration heat duty. The CO2 removal efficiency in a rotating packed bed was observed to be more suitable than that in a packed column, suggesting a potential of a rotating packed bed can replace a traditional packed column to the usage of reduction of the greenhouse gas CO2 from the exhausted gas. The mixture containing PZ and DETA exhibited a high CO2 removal efficiency among these absorbents. Besides, DETA has a lower regeneration heat duty than MEA, which means the finest mixture for industrial CO2 capture system will be the combination of PZ, DETA, and ionic liquids, instead of traditional alkanolamines, MEA.

Anthropogenic CO2 emissions has led to global climate change and widely contributed to global warming since its concentration has been increasing over time. It has attracted vast attention worldwide. Currently, the different CO2 capture technologies available include absorption, solid adsorption and membrane separation. Chemical absorption technology is regarded as the most mature technology and is commercially used in the industry. However, the key challenge is to find the most efficient solvent in capturing CO2. This paper reviews several types of CO2 capture technologies and the various factors influencing the CO2 absorption process, resulting in the development of a novel solvent for CO2 capture.

To address the issue of global warming and climate change issues, recent research efforts have highlighted opportunities for capturing and electrochemically converting carbon dioxide (CO2). Despite metal doped polymers receiving widespread attention in this respect, the structures hitherto reported lack in ease of synthesis with scale up feasibility. In this study, a series of mesoporous metal-doped polymers (MRFs) with tunable metal functionality and hierarchical porosity were successfully synthesized using a one-step copolymerization of resorcinol and formaldehyde with Polyethyleneimine (PEI) under solvothermal conditions. The effect of PEI and metal doping concentrations were observed on physical properties and adsorption results. The results confirmed the role of PEI on the mesoporosity of the polymer networks and high surface area in addition to enhanced CO2 capture capacity. The resulting Cobalt doped material shows excellent thermal stability and promising CO2 capture performance, with equilibrium adsorption of 2.3 mmol CO2/g at 0 °C and 1 bar for at a surface area 675.62 m2/g. This mesoporous polymer, with its ease of synthesis is a promising candidate for promising for CO2 capture and possible subsequent electrochemical conversion.
