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.

Summary Adsorption technology is very attractive for producing desalinated water and cooling with no harmful impact on the environment. The performance of adsorption water applications (desalination and cooling) depends on the adsorption characteristics. Many adsorption systems designs were investigated worldwide, employing different adsorbent materials to develop a cost‐effective and high‐performance system. This review presents and summarizes the studies in adsorption and the corresponding applications in desalination and cooling and compares the adsorption properties of composite adsorbents. The review focuses on the composite materials and how they were synthesized while comparing them in terms of the amount of adsorption. The reviewed materials have been classified according to the basic host, such as silica gel, zeolite, carbon, metal‐organic frameworks (MOF), and vermiculite. The review contains more than 70 composites. The maximum reached water vapor uptake is 1.92 kg/kg of PHTS/CaCl2‐20 wt% composite at 0.9 P/Ps. The highest available desorption amount is 1.48 kg/kg of MOF composite for desalination applications and 0.87 kg/kg of vermiculite composite for cooling applications.
