Abstract
The composition of products formed in the discharge chamber at the synthesis of nanostructures by arc discharge was investigated. The fullerene soot obtained in an argon atmosphere was shown to contain at least three structural phases: amorphous carbon, fullerenes, and graphitized particles. In the process of thermal desorption, the water and oxygen adsorbed from the atmosphere, as well as carbon oxides generated at the oxidation evolve from the argon soot. By the reactivity, the fullerene black obtained in different buffer gases form a series: special helium, argon, usual helium. The cathode deposit of the arc discharge in argon, as in helium, contains multiwall nanotubes in its soft parts.
