Synergistically Enabling Fast‐Cycling and High‐Yield Atmospheric Water Harvesting with Plasma‐Treated Magnetic Flower‐Like Porous Carbons

Sorption‐based atmospheric water harvesting (AWH) offers a promising solution to the water scarcity in arid regions. However, majority of the existing AWH sorbents are suffering from rather poor water productivity due to their slow water adsorption–desorption cycling capability especially when they...

description Sorption‐based atmospheric water harvesting (AWH) offers a promising solution to the water scarcity in arid regions. However, majority of the existing AWH sorbents are suffering from rather poor water productivity due to their slow water adsorption–desorption cycling capability especially when they are applied in high packing thickness. Herein, an oxygen plasma‐treated magnetic flower‐like porous carbon (P‐MFPC) with large open surfaces, abundant surface oxygen‐containing moieties, and excellent localized magnetic induction heating (LMIH) capacity is developed. These merits, together with the use of air‐blowing‐assisted water adsorption and LMIH‐driven water desorption strategy, synergistically allow P‐MFPC with 2 cm of packing thickness to complete a AWH cycling in 20 min and deliver a record 4.5 L(H2O) kg(−1) day(−1) of water productivity at 30% relative humidity. Synergistically enabling such an ultrafast AWH cycling at high sorbent packing thickness provides a promising way for the scalable high‐yield AWH with compact AWH systems.
