Silver Nanorods Synthesis by using Silver Nitrate, Rice grain and CTAB via Seed Growth Method

Silver Nanorods Synthesis by using Silver Nitrate as precursor, Rice grain as reducing agent and CTAB as stabilising agent via Seed Growth Method

1. CHECK LIST

   Silver Nitrate, Rise grain, Cetyl trimethyl ammonium bromide (CTAB), NaOH, Deionized Water, RB Flask, Dropper, Magnetic Stirrer.
   
2. STEP 1.

   Take 2g of rice grains in 10ml of water and boil at 100°C for 1 hours to prepare starch solution.
   
3. STEP 2.

   Take 5mg of Silver Nitrate in 10ml and add 0.6ml of starch solution, setup the reflux at 50°C for 2 hours, to prepare seed solution
   
4. STEP 3.

   Take 50mg CTAB in 7ml of water, add 0.5ml starch solution into it.
   
5. STEP 4.

   Add 0.01mg Silver Nitrate in 0.5ml of water and add it in the solution prepared in step-3. This is growth solution.
   
6. STEP 5.

   Add 1ml of seed solution (prepared in step-2) in growth solution (prepared in step-4).
   
7. STEP 6.

   Add 20mg NaOH in 0.5ml water and add it into solution prepared in step-5 (pH~11).
   
8. STEP 7.

   Stop stirring and keep the solution (prepared in step-6) untouched for 2 hours at 30°C.
   
9. RESULTS

   Silver Nanorods should be having a diameter of ~ 20 nanometers and length of ~ 100 nanometers.
   
10. NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
