At present synthesis of carbon nanostructures is mainly performed in different scientific groups by any one method. For this reason not everyone has possibility to compare peculiarities of synthesis of the same product by different methods. The most of investigations of physical and chemical peculiarities of nanostructure formation and morphology of nanostructures has been performed by two methods: pyrolysis of hydrocarbons and arc evaporation of graphite in liquid phase. Peculiarities of carbon nanostructure synthesis and the effect of temperature and cooling rate of the product on its formation and morphology have been investigated in this work. We have compared the peculiarities of formation of the nanostructures synthesized by the arc method in gaseous and liquid helium to understand the effect of the state of medium on the process of nanostructure formation. From the aforesaid, it might be assumed that the discussed method of carbon nanostructure synthesis is sufficiently productive. It allows the production of nanostructures and composites based on them with different morphology, different properties and consequently for different applications. In this case during the reaction many carbon nanostructures, that are interpreted to be the by-product, have no time to form or grow because of a high rate of the temperature change.
