| contents | Covalent Organic Frameworks for Water Harvesting from Air Fuxiang Wen Ning Huang ChemSusChem AbstractDespite approximately 70 % of the earth being covered by water, water shortage has emerged as an urgent social challenge. Sorbent‐based atmospheric water harvesting stands out as a potent approach to alleviate the situation, particularly in arid regions. This method requires adsorbents with ample working capacity, rapid kinetics, low energy costs, and long‐term stability under operating conditions. Covalent organic frameworks (COFs) are a novel class of crystalline porous materials and offer distinct advantages due to their high specific surface area, structural diversity, and robustness. These properties enable the rational design and customization of their water‐harvesting capabilities. Herein, the basic concepts about the water sorption process within COFs, including the parameters that qualitatively or quantitatively describe their water isotherms and the mechanism are summarized. Then, the recent methods used to prepare COFs‐based water harvesters are reviewed, emphasizing the structural diversity of COFs and presenting the common empirical understandings of these endeavors. Finally, challenges and research concepts are proposed to help develop next‐generation COFs‐based water harvesters. 10.1002/cssc.202400049 http://onlinelibrary.wiley.com/termsAndConditions#vor |
