Synthesis of Tungsten(VI) Oxide (WO3) Nanorods via Hydrothermal

Synthesis of Tungsten(VI) Oxide (WO₃) Nanorods via Hydrothermal
  1. CHECK LIST
    Sodium Tungstate (Na2WO2.2H2O), Oxalic Acid (H2C2O4.2H2O), Hydrochloric Acid (HCl), Potassium Sulfate (K2SO4).
  2. STEP 1.
    Take Sodium Tungstate (2g) and Oxalic Acid (1.5g), add these in 50 ml of deionized water.
  3. STEP 2.
    Add HCL in the above solution until the pH reaches around 0.8, after this transparent homogenious solution is formed.
  4. STEP 3.
    Add Potassium Sulfate (3g) into the solution.
  5. STEP 4.
    Tansfer the solution in Hydrothermal; set the temperature 100°C for 24 hours.
  6. STEP 5.
    Finally, Wash and Filter out the Yellowish solution through centrifuge. You can now use these Tungsten(VI) Oxide (WO3) Nanorods in any application.
  7. RESULTS
    Tungsten(VI) Oxide (WO3) Nanorods color was found to be yellowish. Average diamter of the rods are around 150 nanometers and length of about 1 micrometer.
  8. NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
