With the increasingly severe global water shortage problem, finding alternative freshwater resources needs to be addressed urgently. Atmospheric water harvesting (AWH) technology, a method for obtaining water from the atmosphere, holds great potential in alleviation on the global water shortage problem. The main methods of collecting water from the atmosphere include fog collection, condensation-based AWH, membrane-assisted AWH, and adsorption-based AWH. Herein, the principles of different water collection methods and their respective advantages as well as disadvantages were discussed. The characteristics of different types of adsorbents in adsorption-based AWH technology were compared, and the research progress on composite adsorbents was specifically introduced. At the same time, the optimization and regulation strategies in the processes of water absorption, storage/transportation, and water release were systematically expounded. Finally, the development trends in improving the performance of water collection materials, optimizing water quality, innovating preparation technologies, and expanding intelligent applications were prospected, with the aim to provide useful references and inspirations for further development and application of adsorbents.
