Synthesis of carbon nanostructures using cheap grades of graphite

In the work, carbon nanostructures (CNS) were synthesized on a plasma chemical plant using graphite electrodes SIGE (Special Impregnated Graphite Electrodes) and FGDG-7 (Fine-grained dense graphite) in helium environment. experiments, it was established that of brand are suitable for synthesis CNS by electric arc method. addition, experiments indicate gas environment allows creation centimeter composite rods (deposits), where core consists graphene sheets rolled into nanotubes can withstand extremely high temperatures (>4000 K). Studies scanning microscopy have shown synthetic deposit be divided blocks, which is important its use voltage stations because possible to prepare deposits required length without mechanical impact violating integrity structure. The structure materials studied transmission electron formed during evaporation even catalyst. Experiments confirmed mass yield wall fullerene-containing black grade significantly exceeds results obtained electrodes. Such make more productive expensive nanoproducts (fullerenes fullerene-like structures) It also recorded nanostructures, single-walled formed, positive charge deposited form surface cathode electrode under action an electromagnetic field.
