Adsorption/desorption atmospheric water harvester

Abstract

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.
