Abstract

This research investigates the synthesis and characterization of La-NDC/La-BDC MOF using FTIR, XRD, SEM, and the electronic response of those MOFs to metal ions and oxoanions at the UV-Vis range. This research was conducted in February-June 2022 at the Laboratory of Basic Science, Faculty of Education and Faculty of Science, University of Bengkulu, and Laboratory of Bandung Institute of Technology. MOF was synthesized using the solvothermal method from lanthanum nitrate salt (La(NO3)3.6 H2O) with 2,6-naphthalenedicarboxylic acid (NDC) and Benzene-1,4-dicarboxylic acid (BDC) as ligands and dimethylacetamine (DMA) as a solvent. The reaction was carried out at temperatures 120, 130, and 150 ℃ for 24 h. The result showed that La-NDC MOF had been obtained in the form of yellowish crystals from a reaction at temperatures 120 and 130 ℃; brownish-colored crystals from a reaction at a temperature of 150 ℃; and yellowish crystals from the reaction at all temperatures. The FTIR test on crystals demonstrated no wavenumber at 2500 cm−1 (characteristics of -OH functional groups). In addition, the absorption peak of C = O was shifted from the standard peak. This indicates that the synthesized La-NDC and La-BDC have coordination bonds between La3+ ions and NDC or BDC ligands. The results of the XRD test on crystals indicated a high level of crystallinity. Meanwhile, the SEM test showed that the synthesized crystals had a morphological size that was not uniform for La-NDC and a rod-like form for La-BDC. The La-NDC response test to oxoanions exhibited a new peak at a wavelength of 328 nm–368 nm indicating La-NDC MOF has the potential to be used as a sensor. Besides, La-BDC was shown to be selective toward Fe3+ and Al3+ ions.
