Research advances on the adsorption and separation of isotopes by porous organic framework materials.

The research progress of porous organic framework materials, represented by metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), used as novel adsorbents in the separation of gas-phase isotope and liquid-phase isotope in recent years is reviewed, the difficulties in the present study are clarified, and the future development trend is prospected, which provides reference for further research on the application of MOFs/COFs in isotope adsorption and separation.
