Abstract
A method of producing graphene sheets comprising the steps of, (a) forming a carbonaceous powder by electrochemical erosion of a graphite electrode in a molten salt comprising hydrogen ions, (b) recovering the resulting carbonaceous powder from the molten salt liquid, and (c) thermally treating the carbonaceous powder by heating the carbonaceous powder in a non-oxidising atmosphere to produce a thermally treated powder comprising graphene sheets.
