Application of surfactants in the preparation of MOFs
Metal-Organic Frameworks(MOFs)have outstanding advantages such as large specific surface area,adjustable pore size and controllable properties.MOFs have a wide range of applications in gas storage,adsorption and separation,catalytic reactions,sensing,etc.Surfactants can be employed in the preparation of MOFs to control the size,pore size and geometry of the crystals.Surfactants can also limit the longitudinal growth of the nanocrystals and promote the formation of 2D structures.Moreover,the MOFs thus prepared have a stable structure and are not prone to collapse.In this review,the applications of conventional surfactants and special surfactants such as Gemini surfactants and ionic liquid surfactants in the preparation of MOFs as templating agents and capping agents were reviewed.The roles of surfactants in precise control of the morphology and porosity of hierarchically porous MOFs were prospected,as well as those special surfactants and their applications.This review pointed out the direction for application of surfactants in preparation of MOFs and provide more pathways for preparation of MOFs.
