Abstract

Coordination polymer have been attracting considerable attention and present a great potensial in photocatalytic water treatment, paving the way for buliding efficient and enviromentally friendly photocatalysts. In this work, samarium complexes constructed from 2,6-naphtalenedicarboxylate ligand was successfully synthesized using solvothermal methode. Samarium complexes are characterized by Powder X-ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR), Uv-vis Diffuse Reflectance and Cyclic Voltametric. FTIR characterization results indicate peak absence of absorption band arround 1700 cm-1 further confirms that the carboxylate groups in dicarboxylate ligand are completely deprotonated. The value of the band gap obtained from the corresponding transition is 3,1 eV. The LUMO Level reduction potential O2/O2 -∗ is obtained-2.1 volt, this value is more negative than the potential standard O2/O2 -∗ reduction is-0,33 volt, so the ability to form O2 -∗ is greater. Based on the characteristics obtained, this material potential as a semiconductor for photocatalysts methylene blue degradation, where samarium complexes in 240 minutes can degradation methylene blue by 68,6 percent.
