Method of manufacturing carbon nanofiber and apparatus for manufacturing the same

A method of manufacturing a carbon nanofiber comprising:

• dissolving a catalyst-precursor and a supporter-precursor into a solvent of a hydrocarbon-based compound to prepare a reacting solution;
• atomizing the reacting solution;
• thermally decomposing the atomized reacting solution to forming particles of the carbon nanofiber;
• and
• collecting the particles of the carbon nanofiber,
• wherein the atomizing of the reacting solution is performed by an ultrasonic spraying method, and wherein the ultrasonic spraying method receives a first carrier gas from an external resource for the first carrier gas and transfers the atomized reacting solution by the first carrier gas.

An apparatus for manufacturing a carbon nanofiber comprising:

• a solution-generating unit that mixes a catalyst precursor and a supporter-precursor with a solvent of a hydrocarbon-based compound to form a reacting solution;
• an atomizing unit that receives the reacting solution from the solution-generating unit and atomizes the reacting solution;
• a thermal decomposing unit that receives the atomized reacting solution from the atomizing unit and thermally decomposes the atomized reacting solution to form particles of the carbon nanofiber;
• a collecting unit that collects the particles of the carbon nanofiber,
• wherein the atomizing unit includes an ultrasonic spraying apparatus having a first inlet for receiving a first carrier gas from an external resource for the first carrier gas separate, the first carrier gas being used for transferring the atomized reacting solution to the thermal decomposing unit.
