✦ Synopsis

Single-walled carbon nanotube samples were synthesized with solar energy. The products are characterized by electron microscopy, Raman spectroscopy and nitrogen isotherms. The maximum value of the hydrogen uptake is 1 wt.% at 253 K and 6 MPa. The results are discussed by taking account of the structure and the BET surface of the samples. The hydrogen capacity is not proportional to the BET surface in these samples and does not seem to be linked to the amount of SWNT.
