Abstract: | Bundles of pure carbon nanofibers were prepared by catalytic decomposition of acetylene on foam Ni. The morphological and
structural characteristics of the carbon nanostructures, in the as-prepared state, were analyzed by scanning electron microscopy
(SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HTEM). A special conformation
of carbon nanofibers composed of segmented structures was found among the products by both SEM and TEM observations. Further
HTEM examination indicated that the segments were stacked with well ordered graphite platelets arranged perpendicular to the
axis of the filaments.
