Silver Nanocubes Synthesis by using Silver Nitrate as Precursor, Polyvinylpyrrolidone (PVP M.W.:40,000) as Stabilising Agent and Ethylene glycol as reducing agent via Chemical Reduction Method.

CHECK LIST

Silver Nitrtae, Polyvinylpyrrolidone (PVP M.W.:40,000), Ethylene Glycol, HCL, Deionized Water, RB Flask, Dropper, Magnetic Stirrer.

STEP 1.

Take 25ml Ethylene glycol and heat at 130°C for 60 minutes.
STEP 2.

Add 5ml HCL and stirrer for 15 minutes.
STEP 3.

Add (0.25g in 15ml) PVP solution and (0.24g in 15ml) Silver Nitrate solution both simultaneously drop by drop slowly in the solution prepared in step-2.
STEP 4.

After 12 hours, the color changes to transparent indicates the nucleation of Nanoclusters.
STEP 5.

The RB flask was then left without stirring for 10 hours and the red brown solution indicated the formation of Silver Nanocubes.
STEP 6.

Wash Silver Nanocubes by using Centrifuge the at 6000 rpm with acetone:waster (2:1) mixture.
STEP 7.

Silver Nanocubes can now be dispersed in Methanol by using Sonicator and used in any desired application.
RESULTS

Silver Nanocubes with around 50 nanometers of size. UV-Vis absorbance will be observed around 430nm.
Factors Affecting Synthesis

Addition of Precursor and Capping Agent: Silver Nitrate and PVP should be added slowly for uniformity of the Silver Nanocubes.
Molecular Weight of PVP: Molecular weight of PVP will also effect the morphology and size of Silver Nanomaterial.
NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
