Mahdi Ghorbani

I synthesized about three grams of graphene oxide by the method described in the following article:

https://onlinelibrary.wiley.com/doi/abs/10.1002/jssc.201501246

Due to the high acidity of the mixture, the process should be carried out with caution.

Shamsher S. Kanwar

You can definitely scale up the method to synthesize higher amount of graphene oxide. You can follow the article suggested by Mahdi.
