“…The selectivity of CO 2 over N 2 is also sometimes presented, and while these are helpful metrics, flue gas is a complex mixture that contains water vapor and contaminant species, the influence of which is not captured by these metrics. In general, the impact of coadsorbed water in these types of systems is not frequently reported. − Beyond the adsorption capacity and mixed-gas selectivity, the ability to desorb CO 2 from the adsorbent material is critical, and it is helpful when the adsorbent is capable of rapid mass and heat transfer. Additionally, the materials also need to be available in a film or pellet and need to be capable of being produced at a multiton scale at a marketable cost. ,, …”

has emerged as a metal−organic framework (MOF) that is steam-stable and exhibits selective CO 2 physisorption over water vapor, which makes it a candidate for industrial-scale CO 2 capture from flue gases. In this work, multicomponent CO 2 /H 2 O adsorption data show that the α-to-β phase transformation has little impact on the multicomponent CO 2 adsorption capacity of CALF-20. Also, H 2 O isotherms up to 175 °C reveal only limited changes in the water capacity as temperature increases above 45 °C. CO 2 and H 2 O single-component diffusion rates were measured via concentration swing frequency response. The results show that the diffusion rate of water through CALF-20 is similar to that of water diffusion in the highly water-permeable MOF-333, as well as BPL-activated carbon. The data provides key insight into the fundamental thermodynamic and mass transfer parameters that govern the separation of CO 2 and H 2 O using CALF-20 and provides quantified parameters that can be used to model adsorption systems based on CALF-20.

“…Among all the products derived from waste PET, the synthesis of MOF requires special mention. MOFs are inorganic-organic porous functional materials that have rapidly emerged as attractive materials for applications in immune therapy [13], gas separation and storage [14], water treatment [15], super capacitors [16], and barrier properties [17].…”

Graphene Oxide Facilitates Transformation of Waste PET into MOF Nanorods in Ionic Liquids

Although though ionic liquids (IL) are rapidly emerging as highly efficient reagents for the depolymerization of waste plastics, their high cost and adverse impact on the environment make the overall process not only expensive but also environmentally harmful. In this manuscript, we report that graphene oxide (GO) facilitates the transformation of waste polyethylene terephthalate (PET) to Ni-MOF (metal organic framework) nanorods anchored on reduced graphene oxide (Ni–MOF@rGO) through NMP (N-Methyl-2-pyrrolidone)-based coordination in ionic liquids. Morphological studies using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed mesoporous three-dimensional structures of micrometer-long Ni-MOF nanorods anchored on reduced graphene substrates (Ni–MOF@rGO ), whereas structural studies using XRD and Raman spectra demonstrated the crystallinity of Ni-MOF nanorods. Chemical analysis of Ni–MOF@rGO carried out using X-ray photoelectron spectroscopy demonstrated that nickel moieties exist in an electroactive OH-Ni-OH state, which was further confirmed by nanoscale elemental maps recorded using energy-dispersive X-ray spectroscopy (EDS). The applicability of Ni–MOF@rGO as an electro-catalyst in a urea-enhanced water oxidation reaction (UOR) is reported. Furthermore, the ability of our newly developed NMP-based IL to grow MOF nanocubes on carbon nanotubes and MOF nano-islands on carbon fibers is also reported.

Metal‐organic frameworks (MOFs) have emerged as versatile materials with exceptional properties, including high porosities, large surface areas, and remarkable stabilities, making them attractive for various applications. MOF‐5 stands out for its thermal stability and surface area, making it promising for diverse applications, including drug delivery and gas adsorption. This study explores the potential of amino acid MOF (AA‐MOF) composites, integrating phenylalanine, tryptophan, and tyrosine, for selective CO2 and CH4 adsorption using grand canonical Monte Carlo (GCMC) simulations. The impact of amino acid composition and spatial arrangement within MOF‐5 on selective CO2 and CH4 adsorption performance have been investigated. The results indicate that tryptophan‐MOF‐5 exhibits the highest CO2 uptake due to the interaction between CO2 and tryptophan, while phenylalanine‐MOF‐5 demonstrated the lowest affinity for gas adsorption. Radial distribution function (RDF) analysis reveals distinct gas distribution patterns within the composites, with tryptophan playing a dominant role in gas adsorption. Additionally, analysis of total energy, enthalpy of adsorption, and Henry's coefficient provide insights into the thermodynamic aspects of gas adsorption onto AA‐MOF composites. This study enhances the understanding of the fundamental mechanisms underlying CO2 and CH4 selective adsorption in amino acid MOF composites, facilitating the development of efficient gas separation technologies.
