Gas separation membranes are one of the lowest energy technologies available for carbon dioxide from flue gas. Key to handling immense scale this is maximised membrane permeability at sufficient selectivity CO2 over N2. For first time it revealed that metals can be post-synthetically exchanged in MOFs drastically enhance gas transport performance membranes. Ti-exchanged UiO-66 have been found triple without a loss due several effects include increased affinity and stronger interactions...
Membrane separation is a promising technology for extracting temperature-sensitive organic molecules from solvents. However, lack of membrane materials that are permeable toward solvents yet highly selective curtails large-scale applications. To overcome the trade-off between flux and selectivity, additional molecular transportation pathways constructed in ultrathin polyamide membranes using hydrostable metal frameworks with diverse functional surface architectures. Additional passageways...
Synergistic effect of PAF-1 incorporation and photo-oxidation on improving membrane gas separation performance with both high permeability selectivity.
The effect of annealing polycarbonate at 125 °C (≈Tg − 20 K) for aging times up to almost 2000 h has been investigated by differential scanning calorimetry, and the kinetics enthalpy relaxation process are compared with effects same temperature on creep response yield behavior. is analyzed peak shift method, following kinetic parameters obtained: nonlinearity parameter x = 0.46 ± 0.02; apparent activation energy Δh* 1160 kJ mol-1; nonexponentiality β in range 0.456 < 0.6. similarities and/or...
Addressing the mechanical weakness and physical aging of glassy mixed matrix membranes to realise their potential for enhancing separation performance current membrane technologies.
Membranes are particularly attractive for lowering the energy intensity of separations as they eliminate phase changes. While many tantalizing polymers known, limitations in selectivity and stability slightly preclude further development. Mixed-matrix membranes may address these shortcomings. Key to their realization is intimate mixing between polymer additive nonselective transport, improve selectivity, resist physical aging. Polymers intrinsic microporosity (PIMs) have inherently promising...
ConspectusSince the discovery of polymers intrinsic microporosity (PIMs) in 2004, fast size-selective interconnected pore cavities have caused upper bound membrane performance to be revised, twice. Simultaneously, porous materials meant that mixed matrix membranes (MMMs) are now a relatively simple method enhancing transport properties. While there reliable routes with matrices improve fundamental properties materials, many other crucial for separation applications remain largely...
Porous PAF-1 addition accelerated TPIM-2 polymer chain densification and resulted in both improved hydrogen permeability selectivity.
The purpose of this study was to design and develop a self-supporting glass MOF membrane (GMM) including its design, fabrication under different heat treatment temperatures, analysis physical–chemical properties, assessment separation performance. Glass MOFs preserve metal–ligand bonding structures similar their crystalline counterparts, providing intrinsic gas properties alongside the benefits amorphous materials, reduced grain boundaries ease processing. In work, ZIF-62 melted then cooled...
A new pathway to onion-like carbon with narrow, regular and connected pores overcomes the trade-off between power delivery energy storage capacity in supercapacitors.
Post-synthetic exchange (PSE) and defect engineering have emerged as powerful techniques for tuning the properties introducing novel functionality to metal organic frameworks (MOFs). Growing evidence suggests that each technique plays a key role in mechanism of other: linker coordination chemistry is pivotal defective frameworks, while sites can help initiate PSE. Here, intersection these approaches explored by exchanging an MOF with linkers already present within framework. annealing (PSA)...
Novel TFN-FO membranes with improved water flux have been synthesized by adding C<sub>60</sub>@PAF<sub>900</sub> into the organic phase of interfacial polymerization.
It is increasingly apparent that porous liquids (PLs) have unique use cases due to the combination of ready liquid handling and their inherently high adsorption capacity. Among PL types, those with permanent porosity are most promising. Although Type II III PLs economic synthetic methods can be made from a huge variety metal–organic frameworks (MOFs) solvents, these nanocomposites still need stable useful. This work aims systematically explore possibilities creating using different MOF...
Despite the known impacts on climate change of carbon dioxide emissions, continued use fossil fuels for energy generation leading to emission (CO
Metal–organic frameworks (MOFs), with their intriguing network structures, large internal surface areas, and tunable pore properties offer the perfect yet largely unexplored alternative for selective adsorption of oxygen.
Membranes are crucial to lowering the huge energy costs of chemical separations.
Membrane technology without a phase-change process has demonstrated its low-cost, high-energy-efficiency advantages. High fractional free volume polymers of intrinsic microporosity (PIMs), such as poly(1-trimethylsilyl-1-propyne) (PTMSP), are known for high permeability but disappointing gas selectivity. Porous aromatic frameworks and hyper-cross-linked (HCPs) effective membrane additives; however, prior works have examined their performance through chemical interactions other material...
