Sorption-based atmospheric water harvesting offers a potential solution to address global water scarcity. This Review provides a framework for guiding future designs of sorbent materials through understanding key sorption characteristics — capacity, enthalpy, kinetics and stability — derived from the thermodynamic analysis of the interactions among hygroscopic salts, water and salt solutions.
