One-Step Synthesis of Thin Graphite Layers Supported CNTs in Porous Copper by CVD
A novel method is described to synthesize carbon nanotubes (CNTs) –thin graphite layer hybrid materials by a one-step catalytic chemical vapor deposition of acetylene on porous copper bulk. In porous copper, graphite thin layer grows uniformly on the surface of the pores while CNTs sprout out to form a network. As observed by scanning and transmission electron microscopy, the obtained CNTs exhibit bamboo-like multiple-walled structures.
