A Zinc(II) MOF for recognition of nitroaromatic explosive and Cr(III) ion

A bifunctionalised Pb-based MOF for iodine capture and dye removal

“…: 28.42%), attributed to the release of one bdc molecule from the framework and the metal oxide residues remaining. 53 As shown in Fig. 5d, the synthesized and simulated XRD patterns are very similar.…”

“…52 After complexation, moderate intensity peaks were observed at 496 cm −1 and 416 cm −1 , attributed to M–N and M–O vibrations. 53 The band showing absorption maxima at 219 nm could be assigned to the ligand-to-ligand charge transfer (LLCT) or interligand n–π* and π–π* transitions between bdc 2− and the ph-Phen ligand. 54 Upon excitation at 219 nm, an intense emission band was observed at 348 nm, which could be designated to the LMCT (ligand to metal charge transfer) transitions between delocalized π-bond of carboxylate groups and p orbitals of Pb( ii ) atoms (Fig.…”

Nickel nanoparticle-embedded N-doped carbon catalysts formed by MOF derivatives for the oxygen evolution reaction

“…The weak band at about 1280 cm −1 is attributed to C–O vibrations and the absorption band observed near 755 cm −1 is due to O–C–O vibrations of the pydc. 37 The strong bands at 1587 and 1380 cm −1 belonged to the asymmetric and symmetric stretching vibration of the OC–O group, respectively. The peak near 550 cm −1 can be assigned to the typical Ni–O bond.…”

A review of metal–organic framework (MOF) materials as an effective photocatalyst for degradation of organic pollutants

“…2.1 Fundamentals of metal-organic frameworks (MOFs) Metal-organic frameworks (MOFs) are a class of porous materials constructed by metal nodes/clusters and organic linkers, forming numerous architectures. [43][44][45][46] The metal ions can create compounds with unique coordination modes, having tetrahedral, trigonal bipyramidal, square planar, and octahedral geometries. 47 Meanwhile, the most used organic linkers are polytopic carboxylates and other aromatic heterocyclic molecules, facilitating coordination chemistry with the metal ions.…”
