Synthesis and Characterization of Nickel Cobalt Glycerate Derived Nickel Cobalt Based Metal-Organic Framework

This study produced Ni/CO-MOF material from Ni/Co-Glycerate with Ni:Co composition ratios of 1:2, 1:5, and 1:10. The Ni/Co-Glycerate template was synthesized using the solvothermal method at 180°C for 16 hours and dried at 60°C for 6 hours. MOFs were synthesized by dissolving Ni/Co-Glycerate as the metal ion source and 2-mIM as the ligand in distilled water at room temperature. The precipitate was washed with ethanol and dried for 16 hours at 80°C. X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier-Transform Infrared (FT-IR) were used to examine material properties. The XRD results show that increasing the concentration of nickel metal can increase crystallinity, according to increasing intensity peaks at 2θ of 7.19°, 10.30°, 12.39°, and 17.88°. The morphology of Cu/Ni-MOF is hybrid; the hydroxide phase has a flower-like morphology, and MOFs have a circular shape. FT-IR spectra show the same spectrum absorption peaks band. The similarity of the peaks indicates that the functional groups in the Ni/Co-MOF material are the same at different metal concentrations.
