The article provides an overview of metal-organic framework (MOF)-based composite adsorbents for atmospheric water harvesting, discussing the hydrolytic stability of MOFs, recent advances in sorption-based water harvesting devices, and the challenges and prospects of MOF-based composite adsorbents. Key points include compositing MOFs with other functional materials to address limitations in water adsorption capacity and energy-intensive regeneration, and the factors affecting the hydrolytic stability of MOFs.
