“…Further efforts should be made to test the GDEs/electrolyzers with the diluted CO 2 streams with the industrial compositions to analyze which impurities can affect the system the most and what steps need to be taken to improve the stability of the systems in these cases. There are membranes and adsorption systems that are designed to work with corrosive feeds (e.g., NO x and SO x ) 82,83 ; therefore, having a CO 2 ‐selective layer that hinders passing these impurities can protect the catalyst layer which is usually sensitive and poisoned in these cases. Material selection criteria for the CO 2 ‐selective layer. …”

Electrochemical CO2 reduction reaction (CO2RR) has attracted much attention in the last decade, owing to its unique advantages such as operation at ambient conditions, coupling with renewable electricity, and producing a wide range of products and commodities. The majority of CO2RR studies are focused on pure CO2 as feed, while in real CO2 waste streams, such as flue gas or biogas, CO2 concentration does not exceed 40%. Therefore, the economic feasibility of CO2RR and its carbon footprint are greatly limited by the CO2 purification steps before electrolysis ($70–100 per ton of CO2 for CO2/N2 separation). In recent years, studies have exhibited the importance of this matter by integrating CO2 capture and electroreduction in a single unit. Mostly, CO2 capture solutions as electrolytes have been under attention, and promising results have been achieved to significantly improve the overall economy of CO2RR. The focus on CO2 capture‐electroreduction integration can go beyond the solution/electrolyte‐based CO2 capture (e.g., amine solutions and ionic liquids) and other processes such as solid adsorption and membrane‐based processes, as more efficient options, can be potentially integrated with CO2 electroreduction in the gas‐diffusion electrode design. This article aims to review the recent efforts in integrating capture and electroreduction of CO2 and provides new perspectives in material selection and electrode design for membrane‐ and adsorption‐based CO2 capture‐reduction integration, in addition to the analysis of the economic feasibility of this integration.

“…In our composite membrane, the [BAIm] molecule with an acidic site at the C 2 position is sterically in uenced by the nearby third nitrogen group, which has not been studied yet. It has been proven that the nature of the substituent at the C 2 site dramatically in uences cation nucleophilicity thus how easily can be imidazolium-based cation deprotonated with a strong effect on physicochemical properties of IL [29,30].…”

Novel composite membranes based on high-performance poly(ether imide sulfone) (XH-1015, EXTEM™ RESIN) were developed by incorporating 20–60 wt.% of hydrophobic protic ionic liquid, 2-butylaminoimidazolinium bis(trifluoromethylsulfonyl)imide ([BAIm][TFSI]). Structure-properties relationships for the membrane were investigated by using EDS, FTIR, DSC, TGA, and sessile-drop water contact angle measurements. The interaction between the carbonyl group of the imide cycle and imidazolinium cations via hydrogen bonding was evident. The introduction of 20–60 wt.% [BAIm][TFSI] at PEI matrix significantly reduces the glass transition temperature by 84–216°C, respectively, and enhances the surface's hydrophilicity. All the membranes revealed excellent thermal stability up to 400°C. The membranes were tested for their gas permeability as potential gas sensors for CO2 or membrane materials. The unusual transitions of gas permeability mechanism with increasing [BAIm][TFSI] content in the composite were discovered opening a possibility to fabricate a functionally hierarchical membrane for tunable separation of gases from complex mixtures.

“…In fact, the market response to the gas separation membrane techniques has been overwhelmingly positive, with significant growth observed over the past few decades. A recent market analyst report published by Market Research Future ® , reveals that the gas separation membrane industry is projected to grow from USD 2.45 billion in 2023 to USD 4.68 billion by 2030, exhibiting a compound annual growth rate of 10.2% during the forecast period (2023)(2024)(2025)(2026)(2027)(2028)(2029)(2030) (Chitranshi Jaiswal, 2024). The growth of the gas separation membrane market is primarily driven by two key factors: firstly, the increasing number of governmental regulations and laws regarding GHG emissions, with specific restrictions on carbon dioxide emissions across various industrial sectors; and secondly, the expansion of industrial processes such as natural gas treatment, hydrogen purification, and hydrocarbon separation, all of which require gas separation membranes (Chitranshi Jaiswal, 2024).…”
