Tungsten(VI) Oxide (WO3) Nanorods Synthesis by using Sodium Tungstate as precursor and Oxalic Acid via Hydrothermal Method
-
CHECK LISTSodium Tungstate (Na2WO2.2H2O), Oxalic Acid (H2C2O4.2H2O), Hydrochloric Acid (HCl), Potassium Sulfate (K2SO4), Deionized Water, RB Flask, Magnetic stirrer
-
STEP 1.Add 2g Sodium Tungstate and 1.5g Oxalic Acid in 50 ml water.
-
STEP 2.Add HCL in the above solution until the pH reaches around 0.8, after this transparent homogenious solution is formed.
-
STEP 3.Add 3g Potassium Sulfate into the solution prepared in step-2.
-
STEP 4.Tansfer the solution in Hydrothermal and set the temperature at 100°C for 24 hours.
-
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.
-
RESULTSTungsten(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.
