“…The MO removal efficiency was approximately 83% within 60 min. Similar MO removal efficiency was achieved when the catalysts were Co(II)-MOFs [40,41]. As a comparison, the removal efficiency of approximately 93% was achieved with 60 min (figure 7a) in this work.…”

A vapour deposition (VD) method was established for preparation of the UiO-66-supported Fe (Fe/UiO-66) catalyst, which provided the first case of the metal-organic framework (MOF)-supported Fe catalyst prepared by using the vapour-based method. The Fe loading was around 7.0–8.5 wt% under the present preparation conditions. The crystal structure of UiO-66 was not obviously influenced by the Fe loading, while the surface area significantly decreased, implicating most of the Fe components resided in the pores on UiO-66. The results for the methyl orange (MO) removal tests showed that MO in aqueous solution can be removed by UiO-66 by adsorption, and in contrast, it can be oxidized by H 2 O 2 with the catalysis of Fe/UiO-66. Further catalytic tests showed that Fe/UiO-66 was rather effective to catalyse the oxidation of benzene derivatives like aniline in water in terms of chemical oxygen demand (COD) removal efficiency. The catalytic test results for Fe/UiO-66 were compared to those of Fe/Al 2 O 3 with the same Fe loading and to the catalysts reported in the literature. This paper provides a general strategy for VD preparation of MOF-supported Fe catalyst on the one hand, and new catalysts for removing organic pollutants from water, on the other hand.

“…Emission peaks of aromatic organic linkers are generally attributed to the π* → n or π → π* transitions. 35,36 Various pyridyl-appended πconjugated materials have been proven to be highly selective and sensitive chemosensors for toxic ions. 37,38 In our previous works, we prepared a series of CPs by the assembly of 1,3,5-tri-4-pyridyl-1,2-ethenylbenzene with Zn(II) and investigated their performances in the luminescent detection of Cr 3+ ions in aqueous media.…”

Three fluorescent coordination polymers (CPs) including [Zn(ppvppa)(5-NO 2 -1,3-BDC)(H 2 O)] ( 1), [Cd-(ppvppa) Compound 1 has a onedimensional (1D) double-stranded chain structure. 2 and 3 have different two-dimensional (2D) grid-like networks formed by either bridging 1D [Cd(ppvppa) 2 ] n chains with 2,5-FDC ligands or linking 1D [Ni 2 (ppvppa) 2 ] n chains with 5-NO 2 -1,3-BDC ligands. The ligand ppvppa and the three CPs could detect Cr 2 O 7 2− and CrO 4 2− in aqueous solutions by selective fluorescence quenching. The detection limit of the most responsive complex 3 was 1.39 ppb for Cr 2 O 7 2− (pH = 4) or 0.09 ppb for CrO 4 2− (pH = 12), which are below the allowable limits set by the United States Environmental Protection Agency and European Union and the lowest among the known CPs-based sensors. The mechanism of such an emission quenching process may be ascribed to the overlap between the absorption band of the analyte and those of the excitation and emission bands of 3.

“…The rational design and synthesis of novel metal-organic frameworks (MOFs) is currently attracting considerable attention because of their fascinating topological structures and potential applications as functional materials in porosity, catalysis, luminescence, conductivity, magnetism, and so on [1][2][3][4][5][6]. From a synthetic point of view, the judicious selection of appropriate organic ligands is proved to be one of the most effective ways to manipulate the diverse structures of MOFs.…”
