“…All the isotherms were fitted to a dual-site Langmuir model using the Ideal Adsorbed Solution Theory (IAST) 17. CO 2 /N 2 (CH 4 /N 2 ) selectivities were obtained by dividing the CO 2 (CH 4 ) uptakes of the samples by the N 2 uptakes at the same pressure 6,7,9…”

“…Alternatively, ILs can be deposited on the external surface of the MOF to form a core–shell type composite 2. Recently, the IL/MOF composites have been shown to exhibit significantly better performances in gas storage and gas separation applications 3–9. A small number of IL/MOF composites has been reported so far and, extending these investigations to all possible IL/MOF combinations is not possible.…”

“…By scrupulous literature surveys, even though we have found quite a few review papers and book chapters where prime focuses have been devoted to the efficient capture of CO 2 molecules, [ 1,167–180 ] relatively less attention has been given to the summarization of CO 2 separation from gas mixtures. In short, reviews solely based on flue (CO 2 /N 2 ) and biogas (CO 2 /CH 4 ) separations are still missing in the scientific community.…”

Great efforts have been made toward the separation of CO 2 from flue gas and biogas to mitigate environmental pollution and the demand for renewable fuels, respectively. Nonthermal-based separations, such as adsorption-based or membrane-separation technology employing porous materials, are considered to be more promising than traditional cryogenic and absorption-based systems. Due to several advantages of metal-organic frameworks (MOFs) over other conventional porous materials, reports on flue and biogas separation by MOFs are burgeoning (423 for adsorption and 56 for membrane-based separations until June 2021) and demand urgent summarization. This review presents a bird's eye view on such separations while organizing the developed strategies and considering several performance parameters, such as tradeoff between sorption capacity and separation selectivity in adsorption-based systems and permeability versus separation selectivity in membrane-based systems. In addition, the mechanisms involving such separations at the molecular level are presented. A critical discussion section offers more crucial insights into these materials from industrial deployment viewpoints. Finally, future recommendations are made for further developments of MOF materials as flue and biogas separators and thus toward solving both the challenging universal problems of global warming and energy scarcity simultaneously.

“…Metal–organic frameworks (MOFs) as new porous materials have many applications in various fields such as drug storage and delivery (Kotzabasaki & Froudakis, 2018), gas storage (Lee & Bae, 2016; Mohamedali, Nath, Ibrahim, & Henni, 2016), material separation (Mohamedali, Ibrahim, & Henni, 2018), wastewater treatment (Kumar, Bansal, Kim, & Kwon, 2018), and photocatalysis (Subudhi, Rath, & Parida, 2018) due to unique features including high adsorption capacity, suitable biocompatibility, easy preparation and functionalization, and good biodegradability (Cai et al., 2019; McKinstry et al., 2016; McKinstry, Cussen, Fletcher, Patwardhan, & Sefcik, 2013). Application of MOFs as a sorbent depends on the adsorption of pollutants based on an interaction between the pollutant and ligand in MOFs, or penetration of pollutants into the sorbent pores.…”

A novel sorbent based on a mixture of magnetic functionalized graphene oxide and MOFs was developed to remove enrofloxacin (EFX) from water samples. The prepared sorbent was characterized using Fourier transform infrared spectra, scanning electron microscope images, and X‐ray powder diffraction pattern. The sorbent compositions were optimized by the mixture experimental design. Under the optimal condition, the percentages of each sorbent component, including triethylene tetramine‐functionalized graphene oxide (FGO), Fe3O4, and MOF‐5, were 40%, 21%, and 39%, respectively. Besides, the intraparticle diffusion and pseudo‐second‐order kinetic models can describe the EFX adsorption procedure because of two adsorption mechanisms of EFX on FGO and MOF‐5. A positive standard enthalpy of 49.80 kJ/mol indicated the EFX adsorption is endothermic with a chemisorption process. The negative values of ΔGo obtained in the range of −8.979 to −3.431 kJ/mol at all studied temperatures showed that the adsorption process was also spontaneous. The Langmuir and Freundlich isotherm models were analyzed with the partition coefficient to reduce bias in the isotherm model evaluation. The maximum adsorption capacity of 344.83 mg/g and a high partition coefficient of 17.42 g/L in an initial EFX concentration of 10 mg/L were obtained for the EFX removal. Practitioner points Magnetic functionalized graphene oxide @MOF‐5 as a sorbent for the enrofloxacin removal is synthesized. The percentage amount of each component of the sorbent is optimized using the D‐optimal mixture design. Adsorption mechanisms of enrofloxacin on magnetic functionalized graphene oxide @MOF‐5 are discussed. Thermodynamic parameters for the enrofloxacin adsorption with the sorbents are determined. Isotherm model for the enrofloxacin removal with the sorbent is investigated.
