“…Bis(azol-1-yl)alkanes are neutral nitrogen ligands that are often used to prepare coordination polymers. − Bis(1,2,4-triazol-1-yl)alkanes are probably the most widely used among other similar azole derivatives. The system of zinc–carboxylic acid–bis(1,2,4-triazol-1-yl)alkane coligand has been explored by several authors; however, in most cases only one-dimensional (1D), 2D, or interpenetrated 3D structures have been prepared, − which prevented the studies of their sorption properties.…”

Three new zinc three-dimensional coordination polymers with flexible 1,3-bis(1,2,4-triazol-1-yl)propane ligand were synthesized. The crystal structures of synthesized compounds were determined, and structural peculiarities are discussed. Coordination compounds with composition [Zn(btrp)(bdc)]·nDMF are interpenetrated frameworks, while metal–organic framework (MOF) [Zn3(btrp)(bdc)3]·nDMF is not. Thermal stability and luminescent properties of synthesized compounds have been investigated. The possibility of usage of such compounds as sensitive materials for some aromatic compounds are explored, and it was shown that luminescence of coordination polymers is completely quenched in the presence of nitrobenzene. Sorption properties of synthesized MOFs toward nitrogen, carbon dioxide, and hydrogen were evaluated.

“…In recent years, developing new luminescent materials has become a hot topic for new lighting and display technology such as phosphor-converted white light emitting diodes (LED) because of their excellent advantages of eco-friendliness, high efficiency, high power efficiency, long lifetime, and low cost [1][2][3]. The most commercially utilized kind of white LED is the combination of a blue LED chip with a yellow phosphor (Y 3 Al 5 O 12 : Ce 3+ ), which blends the blue light from the chip and yellow light from the phosphor resulting in white light.…”

Sodium samarium borate Na 3 Sm(BO 3 ) 2 , was prepared by a flux method and structurally characterized by single-crystal structure analysis for the first time. The results show that it crystallizes in the monoclinic system P2 1 /n, with a = 6.5667(3) Å, b = 8.7675(4) Å, c = 10.1850(5), β = 90.86 • , V = 586.32(5) Å 3 and Z = 4. The structure contains NaO 7 , NaO 6 , NaO 5 , SmO 8 , and BO 3 units, which are interconnected via corner-or edge-sharing O atoms into a three-dimensional structure. The excitation spectra, emission spectra, decay time, and Commission International de l'Éclairage (CIE) chromaticity index of Na 3 Sm(BO 3 ) 2 were studied. Under near light excitation (406 nm), the powdered Na 3 Sm(BO 3 ) 2 shows the orange-red emission, which originates from the 4 G 5/2 → 6 H 9/2 and 4 G 5/2 → 6 H 7/2 transformation of Sm 3+ ion.

“…The upsurge of interest in the synthesis and design of metal-organic frameworks (MOFs) has been due to their high degree of microporous architecture. They have gained remarkable functions in catalysis, gas storage, and separation [6,7]. Of late, there has been much interest in using the MOF pores for nanoparticle (NPs) encapsulation.…”

Hydrogenation of Carbon Dioxide to Formate Using a Cadmium-Based Metal–Organic Framework Impregnated with Nanoparticles

et al. 2022

The burning of fossil fuels to meet energy demands has increased carbon dioxide (CO2) in the atmosphere, causing global warming and associated climate change. Therefore, new materials are being developed to capture CO2 effectively, limit its impact on the environment, and store and/or utilise it as an abundant C1 building block. In this study, we investigate a cadmium(II) metal–organic framework, [Cd(bdc)(DMF)]n (MOF1), synthesised by treating benzene-1,4-dicarboxylic acid with four equivalents of [Cd(NO3)2]. MOF1 was then used to support Pd, Ni, and Pt nanoparticles in forming MOF1/Pd MOF1/Ni and MOF1/Pt, respectively. These MOF-based materials were characterised using powder X-ray diffraction (PXRD), Fourier-transform infrared (FTIR), energy-dispersive X-ray spectroscopy (EDX), selected area electron diffraction (SAED), and high-resolution transmission electron microscopy (HR-TEM). MOF1/Pd MOF1/Ni and MOF1/Pt proved highly active in the catalytic hydrogenation of CO2 to formate selectively; in contrast, MOF1 did not hydrogenate CO2 to formate. The MOF1/Pd, MOF1/Ni, and MOF1/Pt catalysts produced formate selectively, with the highest TON of 1500 (TOF of 69 h−1) achieved using MOF1/Pd as the catalyst at 170 °C within 2 h. A formate yield of 98% was obtained, which demonstrates that the combination of nanoparticles and MOFs greatly enhances the catalytic activity of the active sites.
