Problems solved by technology

[0014] Using the above arc discharge method, the metal rod wrapped in the graphite rod electrode is also easy to consume and the synthesis yield is low
And because the metal rod is embedded in the graphite rod electrode, it is not in full contact with the growing carbon material in the reaction zone during the arc discharge synthesis process, resulting in a low synthesis yield.

Abstract

The invention relates the preparing method and unit of metal nano material. The unit comprises at least two electric poles, a metal ion source which is installed near electric poles to provide metallic ion current, and a magnetic circuit which is installed between electric poles and metal ion source to control the metallic ion current and make it enter arc discharge zone. The invention also provides the preparing method. The metal ion source and magnetic field used to control metallic ion current is added, so the metal ion can continuously enter the arc discharge zone to sufficiently collide with the active carbon atoms and other atoms, improving the productivity.

Description

【Technical field】 [0001] The invention relates to a method for preparing a carbon-coated metal nanometer material and its equipment, in particular to a method for preparing a carbon-coated metal nanometer material by using arc discharge and its equipment. 【Background technique】 [0002] Carbon-coated metal nanoparticles are a new type of nanomaterials, which have superior magnetic properties when the metal is a transition metal or a rare earth metal. Since the metal nanoparticles are wrapped by carbon and isolated from each other, this structural form not only shows the nano-size effect but also overcomes the thermal and chemical instability of nano-metal materials due to excessive surface energy, so carbon-coated metal nanomaterials It has good electromagnetic properties, thermal stability and corrosion resistance. In addition, since the outer layer of the material contains C=C bonds, which can strongly absorb infrared rays, the carbon-coated metal nanomaterial is applied ...
