In order to achieve the goal of double carbon, CO2 capture should be carried out in a reasonable and efficient manner. Among the common gas separation technologies, membrane separation technology stands out for its advantages of low consumption, small footprint, and environmental friendliness. However, the high preparation cost of inorganic membranes and the trade-off effect limiting the separation performance of polymer membranes have hindered their development, hence the urgent need for high-performance composite membranes.
In order to achieve the goal of double carbon, CO2 capture should be carried out in a reasonable and efficient manner. As one of the common gas separation technologies, membrane separation technology has the advantages of low consumption, small footprint and environmental friendliness. However, the high preparation cost of inorganic membranes and the trade-off effect limiting the separation performance of polymer membranes have hindered the development of inorganic and polymer membranes. Therefore, the urgent need to prepare a high-performance composite membrane has become a current research hotspot. In recent years, 2D nanomaterials have become popular in the field of membrane separation due to their ultra-thin thickness and high specific surface area. This review focuses on membrane materials, starting from the membrane separation mechanism, and mainly introduces the breakthrough research progress of composite membranes with 2D nanomaterials as fillers in the field of gas separation. Finally, the challenges and future development directions of composite membranes in this field are analyzed.
