Fig. 3: Fabrication and characterization of RTS and SLAB.

a RTS is composed of both strong sorbents: Reline and LiCl, which have high sorption capacity and low crystallization temperature. b Crystallization curves of LiCl solution and RTSs. c FTIR spectroscopy curves of LiCl solution, Reline, and RTSs. d Vapor adsorption isotherms for RTS and DES, and theoretical isotherms for LiCl. e Water uptake comparison between RTS and state-of-the-art sorption materials. The detailed information about reported AWH sorbents is listed in Supplementary Table 5. f Schematic of SLAB. g Contribution of different factors to the sorption kinetics enhancement of SLAB. h Sorption kinetics of SLAB under different relative humidities.
