Recent developments in CO ₂ capture, utilization, related materials, and challenges

Abstract

Summary Anthropogenic activities including the combustion of fossil fuels have led to a dramatic increase in the rate of carbon dioxide (CO2) emission in the last three decades. Since fossil‐based fuels are still the predominant energy source for this century, CO2 is a colossal problem. It is emitted as a consequence of combustion and human activities and is a major greenhouse gas (GHG) that significantly contributes to climate change and global warming, making CO2 emission a worldwide problem. The Intergovernmental Panel on Climate Change (IPCC) has proposed a 45% decrease in anthropogenic CO2 emissions by 2030, with a target of “net‐zero” CO2 emissions by 2050. Despite its harmful effects, CO2 has the potential to be used for a wide range of different industrial needs, after its capture. CO2 capture technologies are still in the early stage of development because of economic and technological issues. However, in the future, carbon capture and related application technologies and methods may become easier and more accessible due to the new developments in the materials synthesis, strategies and skills and inexpensive utilization, and functioning cost of the employed methods. Furthermore, carbon capture system (CCS) might improve the recent power plan system properties. Concerning climate change, carbon capture is deemed as a promising solution to prevent CO2 emissions. CO2 capture, storage, and utilization are garnering intensive interest from scientists worldwide. This review paper identifies and gave particular attention to the literature on the recent CO2 capture technologies, for example, adsorption, absorption, membrane, and algae‐based separation techniques for pre‐combustion, oxy‐fuel combustion, and post‐combustion periods. Aside from all of these capture technologies, the utilization and application of captured CO2 in various industrial fields such as solvents, chemicals, and fuels are evaluated.

Carbon Dioxide Capture by Emerging Innovative Polymers: Status and Perspectives

“…Moreover, their structural framework hydrophilicity allows competitive adsorption with water, which strongly impacts their CO 2 capture capability. [31,32] Currently, ILs are gaining prominence as chemical absorbents in post-and precombustion CO 2 capture, attributed to their substantial solubility, a variety of liquid forms, tunability, and thermal stability. ILs are substances composed of entirely ions and possess a melting point below 100 °C.…”

“…[33] ILs have the capability to capture CO 2 through either physical or chemical absorption methods.

“…However, despite their impressive capacity for absorbing CO 2 , porous carbons are limited by their relatively low CO 2 /N 2 selectivity, while zeolites suffer the same as a consequence of their hydrophilic properties and affinity for moisture. [ 32 ] Meanwhile, MOFs, which are composed of metal nodes and organic linkers connected by coordination bonds, have open metal sites that can amplify the effective charge on the metal, thereby strengthening the interaction with CO 2 molecules resulting in enhanced CO 2 adsorption. They also exhibit well‐defined structure, permanent porosity, and impressive tunability.…”

“…[ 33 ] ILs have the capability to capture CO 2 through either physical or chemical absorption methods. [ 32,34 ] One limitation in using ILs for CO 2 capture is their elevated viscosity. Their high viscosity leads to slower absorption rate of CO 2 and typically higher pumping costs which hinders their suitability for industrial CO 2 capture applications.…”
