“…This review aims to focus on the chemistry, engineering, and material science aspects that underpin medium- to high-temperature CO 2 capture using solid oxide materials (e.g., CaO, MgO and Li 4 SiO 4 ) in order to consolidate the current state of understanding of the parameters that drive capture performance; for general overviews of solid sorbents suitable for CO 2 capture at low temperature (<200 °C), e.g., carbon-based materials, zeolites, metal–organic-frameworks (MOF), solid amines or hydrotalcite-like compounds, which all do not necessarily form thermodynamically stable carbonates, we refer readers to relevant review papers. ,,− ,− Figure provides an overview of the most used sorbents for CO 2 capture and their typical working temperature ranges at atmospheric pressure, from which it is apparent that a wide spectrum of process temperatures can be covered. Hence, there is not one universal sorbent that works best for CO 2 sorption in all conditions, but the suitability of a particular type of sorbent is linked to the process (and its infrastructure) that is to be integrated with CO 2 capture, utilization, and storage subprocesses.…”

Carbon dioxide capture and mitigation form a key part of the technological response to combat climate change and reduce CO2 emissions. Solid materials capable of reversibly absorbing CO2 have been the focus of intense research for the past two decades, with promising stability and low energy costs to implement and operate compared to the more widely used liquid amines. In this review, we explore the fundamental aspects underpinning solid CO2 sorbents based on alkali and alkaline earth metal oxides operating at medium to high temperature: how their structure, chemical composition, and morphology impact their performance and long-term use. Various optimization strategies are outlined to improve upon the most promising materials, and we combine recent advances across disparate scientific disciplines, including materials discovery, synthesis, and in situ characterization, to present a coherent understanding of the mechanisms of CO2 absorption both at surfaces and within solid materials.

“…The changes in the climate temperature are irreversible, causing a real threat to the environment and humankind. The emission of gases is one of the most causes of global climate change [1][2][3][4][5][6][7][8][9][10][11] . Gases can be classified as incondensable inorganic gases (i.e., hydrogen (H2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen (N2), oxygen (O2), and noble gases such as He-Kr) and condensable organic gases (i.e., methane (CH4), ethane (C2H6), ethene (C2H4)).…”

“…Greenhouse gases, e.g., CO2, and NOx, are mainly responsible for global climate changes. Among these gases, CO2 emission to the atmosphere from human activities such as breathing, industrial processes, and the burning of fossil fuels is one of the leading causes of global warming [1][2][3][4][5][6][7][8][9][10][11] . Thus, several methods were reported for CO2 capture and utilization (CCU), including adsorption and sequestration [12] .…”

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using ZIFs-based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. Zeolitic imidazolate frameworks (ZIFs)-based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIFs-based adsorbents with high adsorption/conversion efficiencies and tunable properties can be achieved by judicious synthesis and fabrication methods. We reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane synthesis and ways to improve the gas separation performance of ZIF membranes were highlighted. The prospective point of view to promote industrial applications and commercialization of ZIF-based materials was briefly discussed. Once challenges such as low performance and reproducibility for ZIFs-based materials are solved, scalability and cost-effectiveness should not become issues.

“…Many countries have announced pledges to achieve net-zero emissions over the coming decades to bring global energy-related CO 2 emissions to net zero by 2050. Currently, there is high interest in studies of CO 2 capture by adsorption on porous carbonaceous or non-carbonaceous materials [ 1 , 2 , 3 ]. However, the development of commercially available porous adsorbents for CO 2 capture is still in progress.…”

The Application of Hollow Carbon Nanofibers Prepared by Electrospinning to Carbon Dioxide Capture

2021

Coaxial electrospinning has been considered a straightforward and convenient method for producing hollow nanofibers. Therefore, the objective of this study was to develop hollow activated carbon nanofibers (HACNFs) for CO2 capture in order to reduce emissions of CO2 to the atmosphere and mitigate global warming. Results showed that the sacrificing core could be decomposed at carbonization temperatures above 900 °C, allowing the formation of hollow nanofibers. The average outer diameters of HACNFs ranged from 550 to 750 nm, with a shell thickness of 75 nm. During the carbonization stage, the denitrogenation reactions were significant, while in the CO2 activation process, the release of carbon oxides became prominent. Therefore, the CO2 activation could increase the percentages of N=C and quaternary N groups. The major nitrogen functionalities on most samples were O=C–NH and quaternary N. However, =C and quaternary N groups were found to be crucial in determining the CO2 adsorption performance. CO2 adsorption on HACNFs occurred due to physical adsorption and was an exothermic reaction. The optimal CO2 adsorption performance was observed for HACNFs carbonized at 900 °C, where 3.03 mmol/g (1 atm) and 0.99 mmol/g (0.15 atm) were measured at 25 °C. The degradation of CO2 uptakes after 10 adsorption−desorption cyclic runs could be maintained within 8.9%.
