Xenon (Xe) and krypton (Kr) separation is of great interest and plays an essential role in the industry. However, the identical properties and ultra-low concentrations of Xe and Kr are the main challenges related with the separation. Compared with the conventionally used cryogenic process, porous materials-based physical adsorption is promising for efficient and cost-effective separation processes. Herein, this review targets on recent development in the design, synthesis, and Xe/Kr capture and separation performances of metal–organic frameworks (MOFs). We thoroughly evaluate and discuss innovative strategies to enhance Xe/Kr capture and separation in MOFs. Along with the discussions of strategies and developments in MOF, a brief discussion about the advances of computational studies was also provided. Finally, future challenges and prospects of MOFs for Xe/Kr capture and separation are highlighted. We believe that this review will effectively guide readers in the design and selection of suitable MOFs for Xe/Kr adsorption and separation in future endeavors.
