Synthesis of fullerenes by hollow cathode arc
MetadataShow full item record
The formation of fallerenes in a hollow cathode arc in an inert gas atmosphere is investigated. The effects of the carbon evaporation rate, the inert gas flow rate and the are temperature on the fullerene yield, production rate and conversion rate are observed. A magnetic field of 100 Gauss is used to collimate the discharge and to improve the carbon evaporation rate. The agreement among experimental data and theoretical results of the model based on the equations of Smoluchovski is obtained.
