Abstract
Abstract Sorption‐based atmospheric water harvesting is an attractive technology for exploiting unconventional water sources. A critical challenge is how to facilitate fast and continuous collection of potable water from air. Here, a bio‐based gel (cellulose/alginate/lignin gel, CAL gel), resulting from the integration of a whole biomass‐derived polymer network with lithium chloride is reported. A fast adsorption/desorption kinetics, with a water capture rate of 1.74 kg kg −1 h −1 at 30% relative humidity and a desorption rate of 1.98 kg kg −1 h −1 , is simultaneously realized in one piece of CAL gel, because of its strong hygroscopicity, hydrophilic network, abundant water transport channels, photothermal…
