Carbon nanofibers and carbon nanotubes continue to draw unwavering interest from industrial and
academic communities because of their fascinating properties and their projected application values. This
paper reports a one-step synthesis of high-purity carbon nanofibers with dome-shaped interiors by the
noncatalytic thermal decomposition of acetylene over a copper surface at atmospheric pressure. These
uniquely shaped carbon nanofibers were impurity free, and their dome-shaped interiors could be repeated
with high periodicity throughout the length. In addition, Y-junction and forklike carbon nanofibers with
the same internal structure were also formed as byproducts. The growth of these unique carbon
nanomaterials could be rationalized by a mechanism based on the autocatalytic chemical vapor deposition
of 3D graphene flakes. Preliminary electrochemical measurements indicated that the carbon nanofibers
could be used as the active anode material for lithium-ion batteries, delivering good cyclability and a
reversible capacity of ∼260 mAh/g at the high specific current of 100 mA/g.
