Abstract Water and energy are the cornerstones of human development, with more than half world's population facing water scarcity issues. Atmospheric moisture is widely distributed around globe, rational utilization can create tremendous value. Here, sources hygroscopic materials, methods manufacturing hydrogels, properties these potential applications concluded. To make hydrogels high hydrophilicity, ultrasonic oscillation, freeze drying, spin coating be used as synthesis strategies. The main focus on characteristic parameters uptake, dehydration temperature, conductivity, mechanical stability, swelling behaviors, heat transfer coefficient. These unique features will affect performances assembles, devices, instruments. Subsequently, summarized, such harvesting splitting fuel production, dehumidification, thermal management in electronic solar evaporation, electricity production. Finally, future directions issues interest proposed to promote diverse development relational systems.

Abstract Atmospheric water harvesting (AWH) provides a promising pathway to alleviate global stress. However, in arid areas, how solve the local drought problem while making full use of other wasted energy and improving resource utilization efficiency is still challenge. Here, salt‐based biodegradable photothermal aerogels with vertical channels are constructed efficiently utilize waste heat from photovoltaic (PV) panels for tandem atmospheric passive cooling. Specially, hydrogen bonding interactions ionic cross‐linking aerogel porous skeleton together ensure material's stability. This has high‐water adsorption capacity (1.4–5.7 g·g −1 at 30–90% relative humidity (RH)), solar‐powered production up 1.80 ·day . After integrating PV panels, collection evaporation processes result fresh‐water 0.033 kg·m −2 ·h , panel power generation increases by 2.9%. work demonstrates great potential AWH technique combined cooling fully low‐grade energy, promoting development advanced energy‐water cogeneration.
