| Atmospheric water harvesting is pivotal in addressing water scarcity in arid regions. The working principles of solar-thermal-driven adsorptive atmospheric water harvesting systems and key factors influencing their performance are discussed in this study. The functional structures, water harvesting capabilities, and optimal adsorption conditions of various adsorbents are summarized. Their merits and limitations are comparatively analyzed. The analysis underscores the significance of adeptly integrating adsorbent substrates, thermally conductive materials, and hygroscopic salts to augment the efficacy of composite adsorbents. To enhance their performance, several recommendations are made, including the modification of activated carbon, functionalization of graphene, development of composites comprising silica gel, aerogel, and metal-organic frameworks, copolymerization of diverse monomers for improved hydrogel efficiency, and formulation of composite hygroscopic salts with zeolites/porous materials. The proposed strategies provide valuable insights for advancing research on solar-thermal-driven adsorptive atmospheric water harvesting technologies. |
