Hello,
What are the the best methods (in terms of time and complexity) to exfoliate graphite to synthesize graphene?
I have tried to do it using DMF as a solvent aplplying sonication followed by washing and filteration. As the XRDs of both reactant and product are typical, it did not work out well. I probably did the mistake of taking all the solid product inc graphite preciptate at the bottom while I only should have used the suspended graphene layers. I am not sure if this interpetation is accuarte enough.
Any thoughts or ideas are appreciated!!
We use the procedure reported here: https://www.mdpi.com/2079-4991/12/11/1801
It works well to produce few-layer graphene from graphite. Here we used IPA and water. Hope this helps.

Thank you very much. It seems that the centrifugation you have done is critical to the success of producing graphene. Am I correct to presume that the first-sonication precipitate is actually a waste (still graphite) while the 2nd supernatant product that was collected in the 2nd centrifugation step is the actual few-layered graphene?
