“…Additionally, the composite raised MIL-101(Cr)’s diffusion coefficient from 0.674 × 10 –10 cm 2 s –1 to 2.17 × 10 –10 cm 2 s –1 , which significantly sped up the adsorption rate. Compared to active alumina, 13X molecular sieves, and 3A molecular sieves, the water adsorption of the calcium alginate/MIL-101(Cr) composite adsorbent created by Askarieh et al was 290%, 250%, and 350% higher, respectively. As a result, it became a competitive adsorbent in adsorption applications.…”

“…As a result of impregnating MIL-101(Cr) in a 15% LiCl and 25% CaCl 2 solution, a composite was created that had good adsorption performance and a quick adsorption rate. As shown in Figure 13, Askarieh et al 92 employed a calcium chloride solution and sodium alginate to ion gel-process MIL-101(Cr) into spherical beads with an average size of 2.1 ± 0.2 Numerous techniques to enhance the thermal characteristics of MOF materials have been published in recent years. The preparations of MOF coatings and composite thermal conductivity boosters stand out among them as the most important ones.…”

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.

Among the existing metal–organic frameworks (MOFs), MIL‐101(Cr) is renowned for its stability in air and water. As a result, MIL‐101(Cr) has numerous potential applications ranging from adsorptive cooling to catalysis. The industrial‐scale production of MIL‐101(Cr) is necessary before realizing these applications. Yet, there remain two main bottlenecks in preparing MIL‐101(Cr) in bulk: the toxicity of hydrofluoric acid (HF) used in conventional MIL‐101(Cr) synthesis and the challenge of ensuring that the as‐prepared MIL‐101(Cr) is highly porous with specific Brunauer–Emmett–Teller surface area (SBET) above 4000 m2 g−1. On the laboratory scale, MIL‐101(Cr) often presents SBET 2300–3500 m2 g−1. The synthesis and purification procedures often influence the yield, particle size, porosity, and other properties of MIL‐101(Cr). This critical review examines trends in MIL‐101(Cr) preparation procedures and the MOF's resulting properties to elucidate areas for improvement toward its real‐world applications. The purification processes for conventional HF‐based MIL‐101(Cr) whereby porosities vary despite the same synthesis approach are first investigated. Next, the reported additives for substituting HF and their influence on the resulting MIL‐101(Cr)’s porosity and particle size are discussed. The selection of additives may be application‐specific: exemplified in the examination of MIL‐101(Cr)’s preparation, its corresponding water sorption capacity, and desiccant‐related applications.
