2.3. Synthesis of Nanocomposite magnetic metal-organic framework NiFe2O4@SiO2@HKUST-1
Dispense 1 g of nickel ferrite prepared in the previous section (2.2) with 50 ml of ethanol then add 2 ml (3-aminopropyl triotoxycylan) and under reflux conditions at 80 oC for 6 hours, allow to mix thoroughly and resulting sediment was separated using a magnet.
Pour 1 gram of the resulting powder with 25 mmol of copper nitrate, 22.5 mmol of lycopene tritactic acid (BTC) and 60 ml of distilled water in the balloon and re-mixed under reflux conditions at 100 oC for 8 hours. After washing, the resulting deposit was placed in a vacuum oven at 120 oC for 10 hours to allow the precipitate to dry and the magnetic metal-organic framework nanocomposite (NiFe2O4@SiO2@HKUST-1) formed.
