Metal-organic framework materials (MOFs) have extensive application potential in the field of chemical gas separation. Due to their high specific surface area, adjustable pore structure, and excellent selective adsorption properties, MOFs can effectively separate different types of gas molecules. This paper reviews the research progress of MOFs in gas separation, focusing on their applications in natural gas processing, carbon dioxide capture, and air separation. Regarding the gas adsorption characteristics of MOFs, this study analyzes the influence of different structures on the selectivity of gas molecules and proposes potential paths to optimize the performance of MOFs. The gas adsorption capacity and separation efficiency of MOFs can be improved through strategies such as adjusting porosity and functional modification.
