Abstract
The reaction between lanthanide nitrate (Sm, Eu, and Tb) with Na-PTC in DMF and water at 170 oC solvothermal for 6, 24, and 72 hours resulted in new Ln-MOFs which differed from one another. The new Ln-MOFs were then characterized using FTIR, UV-DRS, TGA, XRD, and SEM-EDX. FTIR and UV-DRS characterization showed that the synthesis time affected the Ln-MOFs structure as seen from the FTIR spectrum shift and changed the band gap value. The three MOFs' XRD patterns showed a polycrystalline structure with about 20 nm with a crystallinity of less than 45% and not found in the X'Pert HighScore 2.1 and Match! 3 software database. This indicates that Ln-MOFs are new compounds. Ln-MOFs are not resistant to high temperatures based on the TGA characterization. The bandgap value for Ln-MOFs is 2.15 - 2.22 eV, so it has the potential as a photocatalyst to degrade dye and produces H2 gas from the water in the visible area. The use of metal lanthanides allows MOFs to have potential as catalysts in organic reactions. However, this potential must be proven by further experiments.
