Abstract Metal-organic frameworks (MOFs) are a class of porous and versatile materials composed of organic ligands coordinated to metal ions or clusters, with potential applications in areas such as gas storage, catalysis, sensors, and drug release. Depending on the choice of organic ligand and metal ion, a wide variety of MOFs with different chemical compositions and structural properties can be synthesized. MOFs containing lanthanides have attracted significant attention in materials science in recent years due to their advantages such as high surface areas, tunable properties, coordination diversities, thermal and chemical stabilities, environmental friendliness, and versatility in applications. Because of the optical properties and electronic structures of lanthanide ions, MOFs containing lanthanides are widely used in photocatalytic applications, particularly those involving processes like carbon dioxide conversion and organic synthesis, as they have the potential to catalyze chemical transformations using sunlight. Although the synthesis and characterization of these materials are challenging, they are known to have significant potential for energy conversion, environmental protection, and sustainable applications in the chemical industry. Present study deals with the synthesis of a MOF composed of benzene-1,4-dicarboxylic acid organic ligand and lanthanum(III) nitrate hexahydrate via the solvothermal method. Subsequent characterization of the MOF was carried out by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX).
