20.500.12556/RUL-134277 High-yield solar-driven atmospheric water harvesting with ultra-high salt content composites encapsulated in porous membrane Sorption-based atmospheric water harvesting (SAWH) is recognized as a feasible and sustainable approach to address global water scarcity in arid regions. However, easy-to-prepare and inexpensive salt-based sorbents have stringent requirements referring to sorption duration and environmental humidity; otherwise, the leakage of salt solution can occur. Here, we develop a composite sorbent with remarkably high salt content of 80 wt % and without the risk of leakage by introducing a polytetrafluoroethylene membrane encapsulation method. The developed composite HSCC-E10 shows both fast sorption kinetics inherent to the matrix of composites and high absorption capacity of hygroscopic salt solutions, achieving ultra-high sorption capacity of 3.75 g/g, 2.83 g/g, and 1.47 g/g for 90%, 70%, and 30% relative humidity (RH), respectively. A lab-scale device is developed demonstrating 560 mL/m2 water yield under outdoor natural sunlight. The applicability of proposed sorbents could pave the road for future middle- or large-scale applications, such as vehicle-mounted and continuous SAWH. atmospheric water harvesting salt content solution leakage sorbent membrane hygroscopic salt pridobivanje atmosferske vode vsebnost soli sorbent razlitje raztopine membrana higroskopska sol true false true Angleški jezik Slovenski jezik Članek v reviji 2022-01-04 14:05:04 2022-01-04 14:05:08 2022-09-13 03:54:20 0000-00-00 00:00:00 2021 0 0 17 str. iss. 12, art. 100664 Vol. 2 Dec. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 628.116:502.3 2666-3864 10.1016/j.xcrp.2021.100664 91975171 RAZ_Shan_He_2021.pdf RAZ_Shan_He_2021.pdf 1 79D9B99C765012BDF3F37A728C3CDCF1 be27a7b2e3d8c99e27326ddf071d0fd968dffce7a2d99ace0706a0ab508524b1 17e1a40b-6d61-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152653 https://www.sciencedirect.com/science/article/pii/S2666386421003866 1 c76d5264-6d5e-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152652 Fakulteta za strojništvo 0 0 0
