Yesterday I synthesized 13 nm colloidal gold nanoparticles using hotplate stirrer (T= 300 C, s= 600 rpm), the solution boiled for a long time (until bubles out). Even it had already ~ more than 1 hours.
Do you have experience what is the temperature and the correct length of time for synthesis gold nanoparticles?
Thank you.
Follow our recent article...
"Size controlled green synthesis of gold nanoparticles using Coffea arabica seed extract and their catalytic performance in 4-nitrophenol reduction"
All the best
Do it at room temperature by adding reducing agent to aq solution of gold chloride.
No need to boil.
Dear @ pawan kumar khana, I hope he is trying prepare gold nanoparticles using turkevich method, in that method they use heat treatmemt while preparing gold nanoparticles (size around 15 nm with monodispersity).
So much progress has been made that room temp is enough
Or if using sod citrate then heat between 70-80 for 1-2 hrs.
More practice more good
Yes Dr. Pawan I completely agree with you, there is lot of reseach is going on...
And practice will give us perfect results
Yes, I was using Turkevich method.
Thank you for your suggestions Dr. @Pawan Kumar and @Naveen Kumar
Those will help me a lot. 👍👍
