Synthesis of Graphene and N-Doped Graphene from Flames

Recently, ames have emerged as a viable alternative method for the synthesis of carbon nanomaterials [10]. The ame can provide a carbon-rich chemically reactive environment capable of generating nanostructures during short residence times in a continuous single-step process. Various ame congurations, fuel types, and catalytic materials have been employed in an attempt to achieve the controlled growth of carbon nanoparticles, multiwalled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs) as well as nanobers, and graphene (Table 33.1).
