Recent advances in multifaceted applications of MOF-based hydrogels

Metal-organic frameworks (MOFs) have recently garnered attention due to their intriguing physiochemical properties; however, their instability and unsatisfactory processability have limited them from achieving a wide range of applications. Therefore, structural new MOFs and MOF-based hydrogels have been developed to address associated drawbacks (such as inherent brittleness and instability in the crystalline state). The development of MOF-based hydrogels has been the focus of some recent attempts. Compared to the original MOFs, they have several better properties (such as improved mechanical strengths). This review will provide the latest overviews of current research developments on MOF-based hydrogels. We primarily focus on the classification of these hydrogels and their associated synergistic effects. We also emphasize microscale composite design, macroscale performance, and extended applications in catalysis, water treatment and biomedicine. Further, we anticipate that this review will be valuable for individuals seeking insights into the applications of MOFs-based hydrogels.
