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

Abstract

A 2-Dimensional Pb(II) metal-organic framework, [Pb(bdc)0.5(py-Phen)NO3]n (SM-3) was synthesized under solvothermal conditions utilizing a mixed ligand approach. SM-3 assembled through dinuclear SBUs [Pb2(COO)2]2-, oxygen donor H2bdc = 1,4-benzene dicarboxylic acid,...

Nanoporous {Pb3}-Organic Framework for Catalytic Cycloaddition of CO2 with Epoxides and Knoevenagel Condensation

“…However, Pb(2) is coordinated by eight carboxyl oxygen atoms from two μ 2 -η 1 :η 1 and four μ 2 -η 1 :η 2 groups, resulting in a distorted antiprism polyhedron. The Pb–O bond lengths are located in the range of 2.315(7)–2.695(6) Å, and the Pb–N bond length is 2.546(8) Å, consistent with previously documented ones. − …”

Metal–Organic Frameworks with Triazine and Amine Functional Groups for Iodine Removal and Sensitive Detection of Cu2+ and Fe3+ Ions

“…Therefore, searching for a high-efficiency adsorbent to remove iodine is of great significance. Previous investigations have shown that there is a strong interaction between functional MOFs (such as MIL-101-NH 2 , MIL-53-NH 2 , MIL-120, or SM-3) and iodine, which is conducive to iodine removal. − Therefore, the sorption experiments were performed in functionals 1 and 2 to evaluate the adsorption capacity under different concentrations of I 2 -cyclohexane solution. The results show that although there are plenty of triazine rings and imine groups within the pores of both 1 and 2 , iodine can be diffused more quickly into the larger one of 2 , thus removing iodine more efficiently.…”

A mini review on metal–organic framework-based electrode materials for capacitive deionization

“…MOFs are a family of porous crystalline materials comprising organic linkers and metal ions/ clusters joined together via coordinate bonds. [21][22][23][24] The physicochemical properties of these materials can be easily controlled by selecting appropriate starting materials (metal ions and organic linkers) and deploying optimal synthesis strategies (hydrothermal, solvothermal, microwave, etc.). [25][26][27][28][29] Hence, it is feasible to introduce a specific functional group to the MOF or engineer an MOF with unique porosity depending upon your requirement.…”
