Abstract

The effective capture of iodine, a byproduct of nuclear fission, is paramount for environmental safety. This study introduces a novel metal-organic framework (MOF), [Y₂(pdc)₄(Me₂NH₂)₂]_n, YS-2, synthesized through a solvothermal reaction involving yttrium metal ions and 2,5-pyridine dicarboxylic acid. The MOF is characterized by its unique scu-3,6-I41/amd and dia; 4/6/c1; sqc6 topology and orthorhombic crystal system. YS-2 exhibits remarkable iodine adsorption capabilities in both vapor and solution phases, measuring 289.53 and 660 mg/g, respectively. Its structural features, including the presence of aromatic rings containing heteroatoms, contribute to its superior performance in capturing iodine. Furthermore, YS-2 demonstrates a remarkable ability to remove dye pollutants, such as methylene blue, from aqueous solutions. This research highlights the potential of YS-2 as a promising material for addressing environmental challenges associated with iodine contamination and water pollution. The better adsorption properties of YS-2 provide insights into its potential applications in environmental remediation.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
