    摘要:

    Metal-organic frameworks (MOFs) are a class of multifunctional materials which have been extensively studied over the past two decades. MOFs are particularly promising as adsorbents for gas storage, selective capture, and separation in light of their high porosity and exceptional tunability with respect to pore structure. Under the guidance of reticular chemistry, tailored materials with expected porosity, pore size, pore shape, and surface functionality may be achieved by making use of ligand design or post-synthetic functionalization. The focus of our research is the design of MOFs with specific pore structure or functionality, aiming at addressing industrially relevant problems relating to molecular capture or separation. Through topology-directed fine-tuning of MOF pore aperture, we are able to achieve materials with optimal pore size for highly efficient separation of hydrocarbon mixtures, including alkane isomers and propane/propylene, with their performance surpassing traditional adsorbents. In addition, judicious post-synthetic functionalization enables MOF materials excellent capability for selective capture of industrial pollutants such as volatile radioactive species. They show superior performance over currently used benchmark adsorbents in terms of adsorption capacity, recyclability, and cost. This talk will focus on developing highly stable MOFs for molecular capture and separation, with an emphasis on material design strategy and capture/separation mechanism.
