N2 - Metal-organic frameworks (MOFs) based on lanthanum metal ions (La3+) and 2,6-naphthalenedicarboxylic ligand (La-MOFs) have been synthesized by solvothermal method at 120 °C and 150 °C for 24 h using dimethylformamide and water (5:1) as a solvent. Furthermore, the chemical bonding and vibration spectroscopy, crystallographic structure, band gap, particle size and microscopic, and redox potential studies of La-MOFs were also investigated as well. FTIR results shown that there were no wave numbers at 1690-1730 cm-1, which affirmed that the La-MOFs had been formed. UV-VIS DRS characterization with solvent (DMF: Water) using (Ln3+) metal was confirmed at 492 nm (2.53 eV). SEM/EDX results shown that La-MOFs have an ultrahigh skeleton and the EDS revealed the composition of La, O, and C atoms that reside within La-MOFs, cyclic voltammetry results shown that LUMO level was-2.5 V vs. H+/H2. Finally, the photocatalytic activity of La-MOFs was performed, which produced 24.99 μmol of H2 after being measured for 4 hours.
