“…The third case studies the effect of the operating pressure by performing the same simulation at a lower pressure of 20 kPa for the Ar-He mixture case. These results were selected based on previous experimental studies [12,15]. In all cases, the net plasma power and the feed rate of the feedstock material were kept constant at 28 kW and 1.0 g/min, respectively.…”

A mathematical model has been developed on the continuous synthesis of fullerenes by direct evaporation of carbon-containing materials using induction thermal plasma technology. The main purpose of this study is to numerically investigate the effect of plasma gas composition and operating pressure on the fullerene formation. The simulation results confirmed that Ar-He mixture plasma is more efficient than argon plasma in terms of the particle evaporation, generation of fullerene precursors, fullerene growth and their annealing, and that low pressure operation would decrease the overall yield rate of fullerenes by enhancing the radial diffusion of carbon vapors towards the reactor walls. Thus an operating condition of relatively high helium content in the plasma gas and elevated gas pressure seems much more desirable for achieving a high yield rate of fullerenes. This conclusion is in line with the experimental evidences reported previously.

Nanoscience and Nanotechnology suggest that many of the current problems involving water quality can be solved or greatly ameliorated using the nanoscale adsorbents, called nanoadsorbents. Innovations in the development of novel carbon nanomaterials like fullerenes, carbon nanotubes, and graphene are among the most exciting and promising materials for water treatment-purification. This chapter gives detailed description of the structure, morphology, and adsorption properties of carbon nanoadsorbents. The textural properties of fullerene, carbon nanotubes, and graphene family are highlighted. A brief description of the effects of the electronic properties in the adsorption capability was inferred as well as how the adsorption of molecules may affect photoelectronic properties of carbon nanotubes.

Synthesis of fullerenes from graphite powders of different grade was studied in a radiofrequency (RF) plasma reactor. Dependence of fullerene yield on the properties and feed rate of precursors and on the helium content of plasma gas was studied in details. The fullerene yield was influenced by the mean size and the thermal conductivity of graphite particles on the one hand, and the helium content of the gas phase on the other. Soot containing fullerene mixture of 5.9% was produced in best conditions found in this work. The main component of the fullerene mixture was C 60 . In addition, it contained about 30% of C 70 (corresponding to a C 60 /C 70 mass
