(approximately the area of 1.3 American football fields!). MOFs have the highest surface areas of any known materials. The high internal SA of many MOFs allows them to adsorb large amounts of liquids and gases. This characteristic enables the use of MOFs in a wide variety of applications including gas storage and release, chemical separation, catalysis, drug delivery, energy conversion, and sensing. Two particularly important applications (to be discussed in more detail below) are the use of MOFs for removing toxic chemicals from water and the capture of carbon dioxide gas. There are more than 115,000 MOFs in the Cambridge Structural Database (CSD) as of March 2023, evidence of the enormous and ongoing academic research output in this field. Despite the fierce pace of research activity, there are few experiments suitable for students just beginning their studies in chemistry (e.g., high school or early undergraduate students) that provide familiarity with and an understanding of the synthesis and properties of MOFs. a) b)
