Patent Images
1. A process for depositing a metal or metalloid onto carbon nanotubes (CNTs), characterized in that it comprises:
- homogenizing a CNT powder in a reactor,depositing on homogeneous CNT powder metal, chosen from tin, aluminum or copper, or metalloid, chosen from silicon, boron or germanium;
by means of a vapor deposition carried out inside the reactor, at atmospheric pressure and at a temperature below 1000°
C., starting from a precursor formed from an alkyl of the metal or metalloid injected into the reactor in the form of gas.

Abstract
The invention relates to a method and a system for depositing a metal or a metalloid on carbon nanotubes (NTC). The method of the invention comprises homogenising an NTC powder in a reactor, and depositing said metal or metalloid on the homogenised NTC powder using a chemical vapor deposition technique implemented inside the reactor from a precursor comprising an alkyl of said metal or metalloid. The method can be used for the production of nanostructured SiC at the surface of the NTC by Si deposition on said NTC.
