“…Water adsorption isotherms for both materials show a hysteresis between the adsorption and desorption branch due to irreversible capillary condensation. Owing to their outstanding water stability, the cycling stability of MIL‐100 and MIL‐101 materials has been extensively studied in the context of adsorption‐driven heat pumps, room chillers, and sea water desalination, revealing a high performance‐stability of these materials . MIL‐100 and MIL‐101 materials have been demonstrated to be superior to traditional water adsorbents such as NaX [Na 86 (AlO 2 ) 86 (SiO 2 ) 106 ], SAPO‐34 [(SiO 2 ) x (Al 2 O 3 ) y (P 2 O 5 ) z ], or silica gel in terms of water uptake and adsorption–desorption kinetics.…”

“…(Ni)MOF‐74 was shown to be a promising candidate for water desalination in a two bed system operating at low evaporation (5 °C) and high regeneration temperature ( T ≥ 110 °C). [63a] The high regeneration temperature is required due to the strong interaction between the adsorbed water molecules and open metal sites, which makes MOF‐74 materials irrelevant for water harvesting applications.…”

“…These models have been proven useful in the optimization of operating parameters in adsorption based desalination processes such as the optimization of the heat source temperature. [63a] We suggest the selection of multiple pressure intervals for the determination of adsorption–desorption kinetics in a way that different adsorption mechanisms predominate within these segments, e.g., around the onset, inflection point and plateau of the area of steep uptake. Such measurements allow for the determination of the boundaries for ideal PSA conditions.…”

Water harvesting from air in passive, adsorption-based devices holds great potential for delivering drinking water to arid regions of the world. This technology requires adsorbents that can be tailored for a maximum working capacity, temperature response, and the relative pressure range in which reversible adsorption occurs. In this respect, metal-organic frameworks (MOFs) are promising, owing to their structural diversity and the precision of their functionalization for adjusting both pore size and hydrophilicity, thereby facilitating the rational design of their water-sorption characteristics. Here, chemical and structural factors crucial for the design of hydrolytically stable MOFs for water adsorption are discussed. Prevalent water adsorption mechanisms in micro- and mesoporous MOFs alongside strategies for fine-tuning of their adsorption behavior by means of reticular chemistry are presented. Finally, an approach for the selection of promising MOFs with respect to water harvesting from air is proposed and design concepts for next-generation MOFs for application in passive adsorption-based water-harvesting devices are outlined.

Metal–organic frameworks (MOFs) are superior sorbents for water adsorption‐based applications. The unique step‐like water isotherm at a MOF‐specific relative pressure allows easy loading and regeneration over a small range of temperature and pressure conditions. With good hydrothermal stability and cyclic durability, it stands out over classical sorbents used in applications for humidity control, water harvesting, and adsorption‐based heating and cooling. These are easily regenerated at moderate temperatures using “waste” heat or solar heating. The isotherm thermodynamics and adsorption mechanisms are described, and the presence of MOFs in the water–air system is explained. Based on six selection criteria ≈40 reported MOFs and one COF are identified for potential application. Trends and approaches in further synthesis optimization and production scale‐up are highlighted. No‐MOF‐fits‐all, each MOF has its own specific step location matching only with a certain application type. Most applications are technically feasible and demonstrated on the bench‐scale or small pilot. Their maturity is benchmarked by their technology readiness level. Retrofitting existing applications with MOFs replacing classical desiccants may lead to rapid demonstration. Studies on techno‐economic analysis and life cycle analysis are required for a rational evaluation of the feasibility of promising applications.
