Recent advancements in ionic liquid based carbon capture technologies

Abstract

Carbon dioxide (CO2) emission reduction is a current hotspot for researchers and innovators owing to an abrupt increase in CO2 concentration in the ecosystem. The current focus of environmental engineers, technologists, and scientists on developing new and emerging technologies to curb greenhouse gas emissions. Ionic liquids (ILs) are increasingly attracting the interest of academia and industries by their performance in separating CO2 from effluent gases as an emerging technology due to their inherent structure tunability and good affinity with CO2. To observe the recent advancements of IL-based technologies current article assesses the latest research developments (2017- 2021) on IL-based carbon capture technologies; a unique query is generated to eliminate garbage data from the basic search. Novel research progress on ILs has been reviewed, considering their potential and capabilities of capturing CO2. Detailed investigation and comparison of IL-based technologies have also been performed, along with their possible estimation of sequestering CO2.
