A new catalytic method to grow multiwall carbon nanotubes by vacuum anneali
ng of C-60/C-70 + Ni films is presented. Films were obtained by vacuum ther
mal deposition of fullerenes and nickel acetate. The results of investigati
ons of films by transmission electron microscopy, electron diffraction and
Raman spectroscopy before and after the annealing process are shown. (C) 20
