How is graphene made from graphite
Web26 feb. 2024 · There are different methods of making graphene oxide, but I’ll talk about the most popular method, the Hummers method. Oxidizing agents like sulfuric/nitric acid and potassium permanganate can be used to exfoliate graphene layers. Small energy input such as stirring can break the graphite into sheets of graphene, forming graphene oxide! Web5 aug. 2016 · To explain, regular graphene is comprised of a two-dimensional, hexagonal honeycomb lattice layer of tightly packed carbon atoms, and is one of the strongest, lightest and most conductive compounds ever discovered. It is considered one of the best materials for supercapacitor electrodes.
