A near solvent-free synthetic route for Ce-UiO-66 metal-organic frameworks (MOFs) is presented. The MOFs are obtained by simply grinding the reagents, cerium ammonium nitrate (CAN) and the carboxylic linkers, in a mortar for few minutes with the addition of a small amount of acetic acid (AcOH) as modulator (8.75 eq, o.5 mL). The slurry is then transferred into a 2 mL vial and heated at 120 °C for 1 day. The MOFs have been characterized for their composition, crystallinity and porosity and employed as heterogeneous catalysts for the photo-oxidation reaction of substituted benzylic alcohols to benzaldaldehydes under near ultraviolet light irradiation. The catalytic performances, such as selectivity, conversion and kinetics, exceed those of similar systems studied by chemical oxidation using similar Ce-MOFs as catalyst. Moreover, the MOFs were found to be reusable up to three cycles without loss of activity. Density functional theory (DFT) calculations were used in order to fully describe the electronic structure of the best performing MOFs and to provide useful information on the catalytic activity experimentally observed. 8 ASSOCIATED CONTENT Supporting Information available.

“…Similarly, Avci-Camur et al [175] have described the water-based synthesis of two types of MOFs (Zr-MOFs and MIL MOFs) using metal acetylacetonate complexes as alternative source of metals. Most recently, Jacobsen et al [176] reported the successful water-based syntheses of a series of Ce (IV) -MOFs (UiO-66, CAU-41 and CAU-44) with three different topologies (fcu, body-centered cubic (bcu), and body-centered tetragonal (bct)) within 30 min via microwave-assisted reactions using six chiral and achiral alkane dicarboxylic C 4 -acids as ligands. In general, the development of a versatile method to fabricate different types of MOFs for future large-scale industrial production is desirable but challenging.…”

Water-based routes for synthesis of metal-organic frameworks: A review

et al. 2020

View full text Add to dashboard Cite

Although metal-organic frameworks (MOFs) show numerous advantages over other crystalline materials, their industrial relevances have been impeded owing to their many drawbacks such as environmental impacts and economic costs of their synthesis. A green preparation pathway could greatly reduce the environmental costs, energy, and the need for toxic organic solvents, and consequently reduce the production cost. Thus, the most desirable synthesis route is the replacement of harsh organic solvents with aqueous solutions to abate environmental and economic impacts. This review summarizes recent research advancements of water-based routes for MOF synthesis and gives a brief outline of the most prominent examples. The challenges and prospects of the commercialization of promising MOFs in the future are also presented. This study aims to offer necessary information regarding the green, sustainable, and industrially acceptable fabrication of MOFs for their commercial applications in the future.

The ligands of (E)-bis(p-3-nitrobenzoic acid) vinyl (C16H10N2O8) were synthesized in three steps, and then the MOF-Zn2(EBNB)2(BPY)2·2H2O was synthesized by solvothermal method. This structure was characterized by X-ray single crystal diffraction, SEM and TG. The drug loading and in vitro release of Zn2(EBNB)2(BPY)2·2H2O were also studied with Methadone as model drug. The results show that the highest loading amount of Zn2(EBNB)2(BPY)2·2H2O to Methadone was 0.256 g/g, and the drug delivery system was a two-phase mode. The results of in vitro cytotoxicity test show that Zn2(EBNB)2(BPY)2·2H2O has good biocompatibility.
