Title:
METHOD FOR PRODUCING GRAPHITIC CARBON NANOCOMPOSITES IN PARTICULAR NANOPEARLS IN BULK OR IN AN INDIVIDUAL MANNER
Document Type and Number:
WIPO Patent Application WO2005009900
Kind Code:
A3
Abstract:
The invention relates a method for producing graphitic carbon nanocomposites consisting in a) preparing a powder of ferromagnetic metal nanoparticles by frozen-ground process, b) filtering the thus prepared powder of ferromagnetic metal nanoparticles in such a way that the calibrated powder of ferromagnetic metal nanoparticles whose mean diameter is equal to or less than 200 nm is obtained, c) deposing said calibrated powder of ferromagnetic metal nanoparticles on a growth medium and d) in growing the graphitic carbon nanocomposites on the growth medium by a chemical vapour deposition process (CDV) wherein the ferromagnetic metal nanoparticles are used in the form of a catalyst.
