Abstract
A novel metal-organic framework based on naphthalenedicarboxylic acid is described. By solvothermal reaction method, 2,6-Naphthalenedicarboxylic acid, existing organic ligands that have never been used to support La-MOFs, was synthesized using acetic acid as the solvent and lanthanum nitrate hexahydrate as a metal source. So far, this type of metal-organic framework based lanthanum ion has not been investigated before. La-NDC MOFs were characterized to determine its functional groups contained in La-MOFs, morphology and particle size, crystallinity, optical and thermal stability by SEM (Scanning Electron Microscopy), FTIR (Fourier transform infrared) spectroscopy, XRD (X-ray Diffraction), UV-vis and TGA (thermogravimetric analysis) sequencely. The adsorption/desorption isotherms of N2 were measured at 77.4 K to know the specific surface area and pore volume of La-NDC MOF. BET (Brunauer-Emmet-Teller) equation was also applied to calculate the surface area of compounds.
