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
