Chemical process of oxidation of the graphite oxide to obtain the graphite, graphene oxide and graphene: use of Fenton like oxidation system.

摘要

Chemical process of oxidation of graphite, graphite oxide to obtain a graphene oxide and graphene system use Fenton like oxidation. Graphite was oxidized by Fenton system (a mixture of Fe2 eh202) to produce graphite oxide.This system is environmentally more favourable than the existing conventional systems, due to the reaction of Fenton occur at room temperature and atmospheric pressure, but also because there is no outgassing during the process of oxidation of graphite.Once formed, the graphite oxide by this method, green, exfoliation of the same in ultrasound room leads to the formation of graphene oxide can then be reduced by a reducing agent, and then form the graphene, a material that has wide application in nanoeletru00f4nic The sensors, supercapacitors, and catalysis.The method of oxidation of graphite described here can be applied in any chemical process for the production of graphite oxide, oxide of graphene or graphene.
