▎ 摘  要

NOVELTY - Producing single or multi layered graphene-containing carbon structures on a surface of the grains of copper powder and/or its alloy by epitaxial techniques in a fluidized bed comprises: mixing copper or its alloy powder containing greater than 80% copper with a grain size of 1 nm to 1 mm, and inert powder with a grain size of 10 nm to 1 mm; annealing at a fluidized temperature of above 750 degrees C under atmosphere containing inert gas, and/or reducing gas contaminants, and gas precursor of carbon at a pressure of 20 mbar to 2 bar; and carrying out thermo-chemical treatment in a sealed fluidizer. USE - The method is useful for producing single or multi layered graphene-containing carbon structures on a surface of the grains of copper powder and/or its alloy. DETAILED DESCRIPTION - Producing single or multi layered graphene-containing carbon structures on a surface of the grains of copper powder and/or its alloy by epitaxial techniques in a fluidized bed comprises: mixing copper or its alloy powder containing greater than 80% copper with a grain size of 1 nm to 1 mm, and inert powder with a grain size of 10 nm to 1 mm; annealing at a fluidized temperature of above 750 degrees C under an atmosphere containing inert gas, and/or reducing gas contaminants, and gas precursor of carbon at a pressure of 20 mbar to 2 bar; and carrying out thermo-chemical treatment in a sealed fluidizer using mechanical vibrations, and/or a gas flow to fluidize the powder mixture.
