Advanced Membrane Materials for CO2 Capture and Separation (en Inglés) - Naiying Du;Haiqing Lin

Climate change caused by anthropogenic CO2 emissions has become a global challenge. The combustion of fossil fuels produces large amounts of CO2 in flue gas, which are released into the atmosphere. To mitigate CO2 emissions, it is necessary to capture CO2 for utilization or sequestration. Membrane-based separation offers an effective approach for CO2 capture due to its high energy efficiency, small footprint, and simplicity in operation and maintenance. However, advanced membrane material designs are still needed to achieve superior CO2 separation performance and reduce the cost of carbon capture.

This Special Issue focuses on recent advances in novel and emerging materials for membrane-based carbon capture. Topics include novel membrane materials-such as polymers, metal-organic frameworks, two-dimensional (2D) materials, and mixed-matrix membranes-for various capture schemes, including post-combustion capture, pre-combustion capture, carbon capture from industrial sources, and direct air capture. It also covers techno-economic analyses, as well as the preparation and characterization of thin-film composite membranes and hollow fiber membranes.
