Research Progress of Metal-organic Frameworks in the Field of Chemical Separation and Analysis

Metal-organic frameworks(MOFs)are known as a class of porous materials which are formed by metal ions and organic ligands through coordination bonds.Extensive attentions have been attracted due to their large surface area,adjustable pores and controllable surface properties and so forth.The surface properties of MOFs can be regulated through selection of organic ligands and metal ions,as well as post-modification.Thus,many applications of MOFs were expanded in separation and analysis field according to improving selective adsorption,specific recognition and other properties.In this review,we focuse on the relationship between the surface properties and separation performance of MOFs,and summarize some relative works in separation and analysis field of MOFs in recent years,and look forward to the future research of MOFs.
