Zinc Oxide (ZnO) Nanoparticles Synthesis by using Zinc Nitrate as precursor and Potassium hydroxide as reducing agent via Chemical Reduction Method.

  1. CHECK LIST
    Zinc Nitrate (Zn(NO3)2.6H2O), Potassium hydroxide, Deionized Water, RB Flask, Magnetic stirrer

  2. STEP 1.
    Make 0.2M Zinc Nitrate solution at room temperature.

  3. STEP 2.
    Make 0.4M Potassium hydroxide solution in another RB Flask.

  4. STEP 3.
    Add Potassium hydroxide solution (prepared in step-2) into Zinc Nitrate solution (prepared in step-1). Stop adding KOH, when white suspension is formed.

  5. STEP 4.
    This white suspension are pre-formed ZnO Nanomaprticles, which can be seperated out at 5000-7000rpm in centrifuge

  6. STEP 5.
    This white powder obtained after centrifuge is calcined at 500°C for 3 hours in air.

  7. RESULTS
    Spherical 30nm size Zinc Oxide (ZnO) Nanoparticles are formed during this process. UV-Vis absorption of ZnO Nanoparticles are around 340nm.

  8. NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
