The graphene particles formed on the metallic particles are of a size and shape substantially corresponding to the size and shape of the metallic particles.

Abstract

A process for producing grapheme is disclosed. The process comprises introducing a solution (102) of a metal alkoxide in a solvent into a decomposition apparatus, wherein the decomposition apparatus includes a first region having a sufficiently high temperature to cause thermal decomposition of the metal alkoxide, to produce graphene.
