摘要

Human-induced emissions demand effective CO2 separation technologies. Energy-efficient membranes, like MXenes with 2D structures, enhance selective gas permeation. This review highlights advancements in improving CO2 retention of MXene membranes, including self-standing, ion-intercalation, and modification techniques. It also examines MXenes in mixed matrix membranes to optimize CO2 permeation. Strategies addressing the selectivity-permeability trade-off, humidified MXenes, and hybrid fillers are discussed, along with challenges and future directions in MXene-based CO2 separation technologies.
