“…[27] The synthesis of metal-containing MOFs was successful and their efficiency in liquid-phase reaction has been largely demonstrated. [24,[28][29][30][31][32][33][34] However, as described by Proch et al, [35] one of the drawbacks of some supports (MOF-177) for the oxidation of alcohol is the sensitivity towards water, which is produced in a stoichiometric way during the oxidation process. Kuhn et al reported on a new class of material, [36][37][38][39] the covalent triazine framework (CTF), which is highly stable in water.…”

A covalent triazine framework (CTF) was used as support for palladium nanoparticles (NPs) and Pd/CTF was applied as the catalyst in the selective oxidation of benzyl alcohol. N groups in the CTF appeared more efficient than those created on carbon nanotubes (CNTs) by NH(3) /high-temperature treatment in stabilizing Pd NPs against growth during the immobilization step. This assured a high metal dispersion, which led to a highly active and stable catalyst in the alcohol oxidation reaction. Indeed, Pd on the CTF was more stable in recycling than Pd on activated carbon (AC) and on nitrogen-doped CNTs, particularly avoiding leaching of Pd NPs. Moreover, Pd on the CTF was less sensitive than Pd on AC to the decrease of reactant concentration. This in turn led to a higher selectivity to benzaldehyde (98 %) with a considerable activity (turnover frequency 1453 h(-1) ).

“…The -OH functionalized MIL-101s name MIL-101-OH was synthesized via grafting utilizing reported procedures [43,47]. Before functionalization, MIL-101 was dehydrated at 150 0 C for 12 h in a vacuum oven to generate CUSs (coordinatively unsaturated sites ).The dehydrated MIL-101 (0.6 g) was suspended in anhydrous toluene (60 mL) in a round-bottom flask equippe with a reflux condenser and a magnetic stirrer, and each of 2 mmol of ETA (Ethanolamine) was added to this suspension.…”

Oxybenzone, one of the most often detected pharmaceuticals and personal care products (PPCPS), from aqueous solutions and this PPCPs removal from water had been studied by using the highly porous metal-organic framework (MOF) ) MIL-101(Cr) and a modified MIL-101(Cr) called MIL-101-OH. Adsorption results showed that MIL-101-OH which contains functional group such as -OH, which was very effective for oxybenzone adsorption. The adsorption performance of MIL-101-OH over MIL-101-OH was found to be greater than that of MIL-101(Cr), which means the functionalization of primitive MOFs have a positive effect on adsorption. The kinetics of MIL-101-OH also showed higher result compare to MIL-101(Cr). So along with a high adsorption capacity and repaid adsorption which is important for commercial applications.

“…In our previous work, it showed that catenated MOFs exhibit high selectivity for the separation of CH 4 /H 2 mixture [18], in which the non-bonded interactions were modeled by Lennard-Jones (LJ) potentials, and no electrostatic interactions were needed to be considered. However, for CO or CO 2 separations it is essential to take the electrostatic interactions into account.…”

“…Owing to their fascinating topologies and various potential applications in industrial technologies, the design and synthesis of MOFs has undergone tremendous development in the past decade [1 3]. According to their structural motifs, MOFs can be categorized into two types: those with non-catenated frameworks [4,5] and others with catenated ones [6,7]. In the latter additional small pores and adsorption sites are formed by the catenation of frameworks, leading to MOFs with multi-pores of different sizes that may exhibit enhanced gas adsorption and separation properties [8,9].…”

In this work grand canonical Monte Carlo simulations were performed to study gas separation in three pairs of isoreticular metal-organic frameworks (IRMOFs) with and without catenation at room temperature. Mixture composed of CO 2 and H 2 was selected as the model system to separate. The results show that CO 2 selectivity in catenated MOFs with multi-porous frameworks is much higher than their non-catenated counterparts. The simulations also show that the electrostatic interactions are very important for the selectivity, and the contributions of different electrostatic interactions are different, depending on pore size, pressure and mixture composition. In fact, changing the electrostatic interactions can even qualitatively change the adsorption behavior. A general conclusion is that the electrostatic interactions between adsorbate molecules and the framework atoms play a dominant role at low pressures, and these interactions in catenated MOFs have much more pronounced effects than those in their non-catenated counterparts, while the electrostatic interactions between adsorbate molecules become evident with increasing pressure, and eventually dominant.
