Large-scale synthesis and hydrogen sorption properties ofsingle-walled carbon nanotubes synthesized with solar energy

摘要

This paper presents a short overview of results about the synthesis of SWNT at small scale using 2kW vertical axis solarfurnace at IMP-CNRS Odeillo. Then, the scale-up methodology is described. A heat transfer model and an experimentalvaporization law of graphite allow to estimate the potential productivity of our 1 MW solar furnace to about 100 g/h.Experiments at medium scale (50 kW) produce about 10 g/h and validate this model.The hydrogen adsorption isotherms of pristine and purified SWNT synthesized at small and medium scale are currently underinvestigation. The results will be presented and discussed in terms of structure and purity.
