“…MOFs are receiving much attentions because of their high porosity, with their pore size/shape being controllable over both microporous and mesoporous regions. The physiochemical properties of MOF materials can be turned with easy modifications or functionalization, which ultimately increases their usability in various applications, such as adsorption [20][21][22] separation [23] and catalysis [24] For example MOFs have recently been successfully used for fuel purification via adsorptive desulfurization [25][26][27] or denitrogenation [28][29][30]. MOFs have also been used for the aqueous-phase adsorption of different pollutants in water, such as heavy metals [31] phosphate [32] organics dyes [33][34][35][36] organic arsenic acids [37,38] bisphenol-A [39,40] and PPCPs (naproxen and clofibric acid) ) [41][42][43] from water.…”

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.

“…13 Crude oil naturally contains sulfur compounds, which are undesirable since they cause SO x exhaust gases. Currently, fuel feeds contain as low as 10 ppmw S and it can be expected that these levels are to be lowered further.…”

Two isostructural microporous metal-organic frameworks [Co(DMA) were synthesized under solvothermal conditions. The structures of both compounds were determined by single-crystal X-ray diffraction data. Each compound adopts a porous three-dimensional framework consisting of square-planar [M 4 Cl] 7+ (M 2+ ¼ Co, 1; Cd, 2) units interconnected by triangular tritopic BTT 3À bridging ligands to give an anionic (3,8)-connected ''Moravia'' net. Phase purity of the compounds was confirmed by X-ray powder diffraction (XRPD), IR spectroscopy, thermogravimetric (TG) and elemental analysis. TGA and temperature-dependent XRPD (TDXRPD) experiments indicate a moderate thermal stability up to 350 and 300 C, respectively. Guest exchange followed by heating led to microporous solids with coordinatively unsaturated metal sites. These unsaturated metal sites create opportunities in adsorptive and catalytic applications. These have been probed by the selective removal of sulfur compounds from fuel feeds as well as the catalytic ring opening of styrene oxide and the oxidation of several cycloalkanes and benzyl compounds.

“…28,29 They observed that MOFs with high porosity absorbed higher concentrations of nitrogen containing compounds (NCCs). [29][30][31] A study reported by Nuzhdin et al 29 indicated that a total of 1.3 mmol of nitrogen containing compounds (NCCs) was removed by 1 g of MIL-101(Cr). Results obtained with the use of molecularly imprinted nanobers in this study could be said to be comparable with the results reported by Nuzhdin et al 29 and some others reported in the literature.…”

Molecularly imprinted polymer (MIP) nanofibers were prepared by the electrospinning of poly 2-(1H-imidazol-2-yl)-4-phenol (PIMH) in the presence of various nitrogen containing compounds (N-compounds). Molecularly imprinted polymer nanofibers show selectivity for various target model nitrogen-containing compounds with adsorption capacities of 11.7 AE 0.9 mg g À1 , 11.9 AE 0.8 mg g À1 and 11.3 AE 1.1 mg g À1 for quinoline, pyrimidine and carbazole, respectively. Molecular modelling based upon density functional theory (DFT) indicated that hydrogen bond interactions may take place between the lone-pair nitrogen atom of model compounds (quinoline and pyrimidine) and the -OH and -NH groups of the PIMH nanofibers. The adsorption mode followed the Freundlich (multi-layered) adsorption isotherm, which indicated possible nitrogen-nitrogen compound interactions. Molecularly imprinted polymer nanofibers show potential for the removal of nitrogen-containing compounds in fuel.
