Tandem Atmospheric Water Harvesting and Passive Cooling Enabled by Hygroscopic Biopolymer‐Based Aerogels

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

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.

Super Moisture‐Sorbent Sponge for Sustainable Atmospheric Water Harvesting and Power Generation

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 7, 2024

Sorption-based atmospheric water harvesting (SAWH) shows great promise to mitigate the worldwide scarcity, especially in arid regions. Salt-based composite materials are extensively used sorbents for SAWH, however, they suffer from complex preparation avoid salt leakage. Furthermore, significant amount of heat produced during process is often neglected and wasted. Herein, an integrated strategy developed synthesis salt-based stable super moisture-sorbent sponge by using chelation LiCl dopamine (DA), simultaneous polymerization DA on melamine (PMS). The as-prepared LiCl/PMS/CNTs showed high uptake, reaching 1.26 1.81 g
