Zinc Oxide (ZnO) Nanorods Green Synthesis by using Zinc Nitrate as precursor and Aloe Vera Leaves as reducing and stabilising agent via Biological Method.
-
CHECK LISTFresh leaves of Aloe Vera Leaves, Zinc Nitrate, Deionized Water, RB Flask, Dropper, Magnetic Stirrer with Temperature option, Filter Paper.
-
STEP 1.Extract the gel from the Aloe Vera leaves to be used as Reducing and Capping agent for the synthesis.
-
STEP 2.Take 30ml Aloe Vera gel and setup reflux at 80°C temperature.
-
STEP 3.Take 3g Zinc Nitrate in 50ml water in another RB Flask.
-
STEP 4.Add Zinc Nitrate solution (prepared in step-3) slowly in Aloe Vera gel (prepared in step-2) by dropper.
-
STEP 5.After some time (~10min) White precipitation star appearing indicated the formation of Zinc Oxide Nanorods.
-
STEP 6.Centrifuge the white precipitate at 5000 rpm for ~15 minutes to collect the powder.
-
RESULTSUV-Vis absorbance of Zinc Oxide Nanorods obtained around 350nm. Diameter of Zinc Oxide Nanorods is around 40nm in size.
-
NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
Instead of zinc nitrate can I use zinc chloride in the same procedure?
You can use any precursor of Zinc but particles shape, size and morphology will change depending on the precursor and reducing agent
