Green Synthesis of Zinc Oxide (ZnO) Nanorods via Aloe Vera

Green Synthesis of Zinc Oxide (ZnO) Nanorods via Aloe Vera

  1. CHECKLIST
    Aloe Vera Leaves, Zinc Nitrate, Water
  2. STEP 1.
    Extract the gel from the Aloe Vera leaves to be used as Reducing and Capping agent for the synthesis.
  3. STEP 2.
    Take Aloe Vera gel (30ml) and setup the reflux at room temperature only.
  4. STEP 3.
    Take Zinc Nitrate (3g) in 50ml of water.
  5. STEP 4.
    Now set reflux temperature to 80°C and add Zinc Nitrate solution slowly in Aloe Vera gel by dropper.
  6. STEP 5.
    After some time (~10min) White precipitation star appearing indicated the formation of Zinc Oxide Nanorods.
  7. STEP 6.
    Centrifuge the white precipitate at 5000 rpm for ~15 minutes to collect the powder.
  8. RESULTS
    UV-Vis absorbance of Zinc Oxide Nanorods obtained around 350nm. Diameter of Zinc Oxide Nanorods is around 40nm in size.
  9. NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
