A review on metal-organic framework nanoadsorbents and their application in dewatering processes

Metal-organic framework nanoadsorbents (MOFs) are a new type of nanoadsorbents with high adsorption capacity. They are interesting for investigators due to their unique characterizations such as very high porosity (more than 90% in pore volume), very high specific surface area (more than 4000 m2/g), different and simple methods for synthesis, adjustable pore diameter, low density, high biocompatibility, high mechanical and thermal stabilities, and finally low energy consumption for adsorbent reduction. Since the dewatering or dehumidification from liquids and gases is used extensively, the adsorbents are introduced and compared with commercial adsorbents such as zeoliths and silicagel. The results showed that the MOFs have high capacity in dewatering due to high stability in aqueous media, proper surface specifications and porosity.
