Samples of single wall carbon nanotubes (SWNTs) were prepared using a solar reactor. Graphite targets containing different catalysts (Ni/Co, Ni/Y, Ni/Ce) allowed the synthesis of SWNTs soot in which nanotubes had different diameter distributions. Sev

This paper aims at the optimum design of a solar reactor for carbon product processing by vaporization. The chosen reference case is the CNRS 1 MW solar furnace and graphite vaporization for fullerene synthesis. The method, which accounts for heat tr

Conventional methods for the synthesis of fullerenes and carbon nanotubes such as laser or electric arc ablation have failed when the process is scaled up. Our ultimate goal is to scale a solar process up from 2 to 500 kW; this paper shows that our m
