Sustainable production and applications of metal-organic frameworks

Metal-organic frameworks (MOFs) have become a hot spot in the area of functional materials and have undergone rapid development in a wide range of fields in the 21st century. However, the scalable application of MOFs is still constrained by high production cost at the front end. Additionally, systematic discussion of the reuse of spent MOFs is lacking. Encouragingly, an increasing number of studies have been focusing on the low-cost production and recycling of MOF-based materials, providing feasible solutions for resource recovery and reduction. To stimulate future enthusiasm and interest in realizing the blue economy of MOFs, ranging from front-end production to terminal disposal, we have presented and summarized the state-of-the-art progress in the sustainable synthesis, separation, and reuse of MOFs. Based on the existing challenges, we also propose fit-for-purpose future directions in the MOF field to move toward blue economy.
