Adsorption/desorption atmospheric water harvester

Harvesting water from ambient air has been an emerging technology to address the critical challenge of water shortage at a global scale. In a recent study published in Cell Reports Physical Science, Wang and colleagues created a novel solar-driven atmospheric water harvester featuring a hydrogel-based composite sorbent (PCLG) and a rationally designed honeycomb structure, which demonstrated a superior water uptake capacity and greatly enhanced vapor transportation efficiency.

High-yield and scalable water harvesting of honeycomb hygroscopic polymer driven by natural sunlightWang et al.Cell Reports Physical ScienceJune 22, 2022In BriefThere remains a large gap between atmospheric water harvesting materials development and their practical application. Here, Wang et al. report a hydrogel-based composite sorbent with high adsorption capacity per unit volume, demonstrated to harvest 2.9 L/m2/day outdoors under natural sunlight as part of an integrated device with a honeycomb structure.
