Highly Conductive Porous Carbon Synthesized by Chemical Vapor Deposition

Amorphous porous carbon was synthesized by the chemical vapor deposition method on copper substrates using methane at atmospheric pressure. Pores have an average size of around 1.2 microns. Lamellar samples of this carbonaceous material have the form and size of the copper foil substrate and can be separated from the support. Electrical resistance as a function of temperature shows a semiconductor-like behavior. We propose that this carbonaceous material may be useful as electrode due to its low electrical resistivity of the order of 0.4 cm at room temperature.
