“…Chemical deployment is required for every framework node and the connecting ligand. 88 Because metal can be partially unsaturated to give specialized adsorption sites and because the size of organic ligands can be changed, MOF can be utilized in the adsorption field to modify the pore volume of the substance. 89 Widespread interest has been generated by the use of MOF in cooling saltwater desalination systems because of its high specific surface area, stable porosity, outstanding hydrophilicity, and low regeneration temperature.…”

The adsorption cooling and desalination system is expected to become the mainstream technology of refrigeration and desalination in the future, because it has significant advantages of low temperature driving and low carbon emission. The system based on adsorption technology merits a small environmental impact and low energy consumption, which can help solve the water and energy crises. More importantly, it can use low-grade heat energy to reduce overall carbon emissions in the working process. The adsorbent is the essential component of an adsorption system, and improving the adsorbent is a vital technological advancement for increasing system effectiveness. Porous materials, such as zeolite, silica gel, and metal–organic frameworks, are the most studied adsorption materials in adsorption cooling and desalination systems. They behave differently regarding stability, thermal conductivity, adsorption capacity, and regeneration temperature. The research status of several different adsorbents, such as zeolite, silica gel and metal–organic frameworks, was comprehensively reviewed and compared. In-depth research was done on several composite adsorption materials’ synthesis processes, characterization, and adsorption traits. The obstacles they experienced were then studied, along with the development trend of composite porous adsorbents. The purpose of this study is to provide a reference for researchers committed to developing new adsorption materials under various applications and conditions.

Adsorption cooling and desalination (ACD) system presents a solution for water, energy, and environmental dilemma. This study expresses an enhancement of adsorption system performance in terms of cooling and desalination effects by improving an activated carbon Maxsorb III (Max) as an adsorbent. Max has been initially treated with HCl. Then, it has been activated by impregnating it in salt hydrates ((NH4)2CO3). Characterization methods, including XRD, N2 and water adsorption isotherm, and water adsorption kinetics have been conducted for raw Max, treated Max, and activated Max with (NH4)2CO3. The experimental values have been fitted with the Dubinin & Astakhov equilibrium model for isotherm and the model of linear driving force for kinetics. These fitted parameters have been utilized in a previously validated model to estimate adsorption cooling-desalination system performance with and without heat recovery. Max/(NH4)2CO3 achieves a water uptake of 0.53 kgH2O.kg-1. Max/(NH4)2CO3 produces 13.2 m3.ton-1 of freshwater per day with a specific cooling power of 373 W.kg-1 and 0.63 COP. Also, the freshwater reaches 22.5 m3.ton-1 of Max/(NH4)2CO3 per day with condenser-evaporator heat recovery. These results indicate the potential of utilizing the Max material in dual cooling and desalination applications to achieve double what silica gel can offer.

“…Water adsorption by different porous materials has been reviewed separately for each class of materials (carbon-based materials, − inorganic materials, , metal–organic frameworks ,, ). In many cases, the reviews were targeted on a specific point of view, synthesis aspect, or particular application. ,, This Review discusses the water adsorption behavior of adsorbents from different classes of materials, that is, inorganic materials (silica, zeolites, (silico) aluminophosphates, and mesoporous silica-based materials), carbon-based materials, and organic–inorganic hybrid materials (MOFs) that are popular in academia. Some of these materials, such as activated carbons, silica gel–water, and zeolite–water systems, are also deployed commercially for different water-related applications.…”

In recent years, the deployment of chemically stable physisorbents in various water sorption-related applications has received significant attention. Depending on their structural features, different types of porous sorbents manifest distinct shapes of water sorption isotherms. The translation of water sorption profiles of adsorbents into appropriate practical applications is yet to be established. This Review gives an overview of the water adsorption studies conducted on different hydrolytically stable porous solids selected from different classes of solid-state materials (organic, inorganic, and hybrid materials). Brief analyses of the water sorption behavior and the relations to materials' intrinsic structural features are made. Based on adsorbents' observed water sorption characteristics, the prospects of their practical/commercial deployment in chosen sectors are also commented. The criteria for using porous adsorbents in specific water-related technologies, which can help guide the design and assembly of suitable water adsorbents, are also reviewed. In addition, the challenges that need to be overcome in developing efficient water vapor adsorbents for a given application are also discussed.
