Enhanced regenerability of metal-organic frameworks adsorbents: Influence factors and improved methods

Metal-Organic frameworks (MOFs) have been the next-generation adsorbent for industrial production and environmental decontamination. However, enhancing the regenerability of MOFs is a bottleneck to achieving their commercialization and industrialization. In this review, a series of standards, such as cycle stability, desorption rate, and regenerative condition, which could comprehensively evaluate the regenerability of MOFs, was adopted. The influenced factors that determine the regenerability of MOFs are concluded, including struc-tural stability, diffusion ability, coordination strength, and thermo-conductivity. Moreover, the classical and novel studies focusing on upgrading the regenerability of MOFs are also summarized, such as enhancing the rigidity of frameworks, accelerating the desorption rate, or decreasing the energy investment. This review will provide guidelines for designing and modifying MOFs adsorbent with superior regenerability. It could also supply theoretical support for investigating the desorption behavior of MOFs.
