Hey guys.I have a question.Do you know some articles about "Exfoliation of graphite" or "Expansion of graphite" with sulfuric acid?If yes , please write the name of that article or doi for that article.

thanks.

 

(HSO4- ) groups enter the crystal between the carbon planes, when graphite is treated with sulphuric acid in the presence of a strong oxidisaing agent.

The product is known as blue graphite.

When subsequently treated with water the graphite is reformed.

An industrial process for the purification of graphite is based on this.

 

 

The advertisers have got hold of the phrase blue graphite so googling this is unproductive.

There are competing purification technologies, which can be found by googling graphite purification.
