Реферат: Nowadays, the Adsorption method for atmospheric Water Harvesting (AWH) is considered a promising heat-driven technology for potable water supply in arid regions. This research focuses on novel composite sorbents based on hygroscopic salts placed inside pores of MIL101(Cr). They have been developed keeping in mind AWH applications. The composites based on LiCl, LiBr, CaCl2, and Ca(NO3)2 were synthesised and comprehensively studied by SEM, XRD, N2 adsorption, and TG methods. The main findings are: (i) CaCl2/MIL-101(Cr) demonstrates high specific water productivity of 0.52-0.59 g_H2O/g_composite per cycle under conditions of Saudi Arabia and the Sahara Desert, which exceeds the appropriate values for other known adsorbents; (ii) the water adsorption on the composite cannot be presented as a linear combination of the adsorption on the components; a synergistic effect is revealed. The performance of AWH employing CaCl2/MIL-101(Cr) was evaluated in terms of the fractions of water extracted and collected and the specific energy consumption, demonstrating its high potential for AWH.
