3. Material Characterization
After synthesis, the magnetic metal-organic framework nanocomposite
(NiFe2O4@SiO2@HKUST-1)
was evaluated. Synthesized samples were evaluated of X-ray diffraction
pattern for structural analysis and phase-type determination (Philips
PNA analytical device, XRD), Fourier transform infrared spectroscopy for
molecular structure and energy determination of chemical bonds
(PerkinElmer), scanning electron microscopy (LEO 1455VP SEM) for fine
analysis structural, transmission electron microscopy (TEM) to determine
microstructures and orientation of crystals, vibrating sample
magnetometer to measure the magnetic properties of compounds, using
thermal analysis (TGA) to analyze the physical properties of materials
under higher temperature and UV-Vis Spectrophotometer
