Résumé

CATALYTIC GROWTH

Nanofibers consisting of repeated units of multiwall carbon nanotubes (MWCNT) with a metal particle encapsulated at one end were synthesized by thermal chemical vapor deposition (CVD) of methane/hydrogen on Ni-Fe catalysts. The grown structures were studied by scanning electron microscopy (SEM), low and high-resolution transmission electron microscopy (TEM). Sequential growth is proposed to explain the periodicity of the nanofibers. The nanofibers are broken by sonication into single elementary units open at one end.
