Abstract: Atmospheric water harvesting based on vapor adsorption is a newly emerged and potential technology to supply portable water for arid areas. To efficiently harvest vapor from the air, sorbents are required to have conside-rable adsorption capacity, easy regeneration and high stability. With the advantages of porous structure, tunable pore size and tailorable hydrophilicity, metal-organic frameworks(MOFs) have demonstrated excellent performance in vapor adsorption and water generation. In this review, we first discuss the degradation mechanisms of MOFs exposed to water and summarize the structure-stability relationship; by centering on the adsorption isotherms, the connection between the structure of MOFs and the water adsorption property is illuminated; finally, some prospects are suggested in order to push forward the progress of this technology.

Key words: Metal organic framework, Atmospheric water harvesting, Hydrolytic stability, Water adsorption isotherm
