A review of metal-organic frameworks (MOFs) as energy-efficient desiccants for adsorption driven heat-transformation applications

Screening of metal–organic frameworks for water adsorption heat transformation using structure–property relationships

“…By using MOF/water working pairs, much signicant progress has been achieved in the elds of adsorption heat transformation. [11][12][13] Furukawa et al 14 prepared a series of zirconium(IV) MOFs by using various organic linkers. Among these materials, MOF-801 and MOF-841 showed the highest water adsorption performance.…”

Dye contaminated wastewater treatment through metal–organic framework (MOF) based materials

“…In the practical application of a designed systematic water treatment plant, time is crucial. 222 The time taken for an adsorbent to reach equilibrium is critical in adsorption technology since the treatment design is directly connected to this duration. One of the most impressive characteristics of MOFs is their capacity to attain equilibrium in a very short period of time.…”

Structure–Property Correlation of Hierarchically Porous Carbons for Fluorocarbon Adsorption

“…Based on sorption mechanism, thermodynamics, kinetics, and environmental perspectives, porous carbon-fluorocarbon sorbent/refrigerant pairs present a prominent potential for sorption cooling due to several reasons. First, porous carbons’ textual characteristics [e.g., specific surface area (SSA), pore volume (PV), pore size distribution (PSD), and the relative ratio of micropore/mesopore] can be versatilely tuned to synergistically boost either the sorbent–refrigerant interaction or the refrigerant–refrigerant cluster adsorption at the micropore (<2 nm) or mesopore (2–50 nm) size regimes, respectively. , Second, additional properties, such as high latent heat, high stability, and low cost, suggest that porous carbons also serve as good candidates . As to the selection of refrigerants, thermodynamic models suggest that low evaporation temperature (below 0 °C) and high latent heat of vaporization benefit from enhancing cooling performance and average cooling capacity. ,,− Meanwhile, the moderate interaction between sorbents and refrigerants could facilitate the mass transfer during the adsorption–desorption process, especially in the mild partial pressure range. , Of the current refrigerants, 1,1,1,2-tetrafluoroethane or CH 2 FCF 3 (R134a) was considered as a model refrigerant as it showed promising cooling applications and also due to its zero-ozone depletion potential, low boiling temperature, easy availability, and relatively low cost.…”
