Metallic photocatalysts are materials that present a metallic behaviour relating to the mobility of the electron in their energy band. Conduction and valence bands in metallic conductors are very close or overlap; thus these materials have a small or absent energy gap separating the occupied and empty energy levels. Graphene, for its turn, is an atom-thick sheet of sp2-hybridized carbons that is considered a zero bandgap semimetal material. It has an electrical band structure that permits a very rapid conduction, i.e. electrons have high mobility with little scattering, thus acting like an electron pool, promoting charge separation and rapid transfer in photocatalytic applications. In this chapter a brief review of the main methods to obtain graphene and derivative graphene oxide and reduced graphene oxide is presented, alongside with examples of their use in photocatalysis.
