Synthesis of Y-shaped carbon nanofiber films by the decomposition of acetylene with copper catalysts

Abstract

In this study carbon nanofiber films were synthesized via chemical vapor deposition with acetylene as carbon resource and copper film as catalyst. The resultant films were characterized using scanning electron microscopy. It was observed that the carbon nanofiber films were composed of a large number of Y-shaped nanofibers, and the diameter of Y-shaped nanofibers was about 300 nm. Copper nanocrystals were always located at the nodes of Y-shaped fibers, and they were faceted with regular shapes, such as triangular and rhombic. Each copper catalyst particle can lead to the growth of three fiber branches over different crystal facets, and thereby form the Y-shaped carbon nanofibers.
