Abstract: PURPOSE: A manufacturing method of a metallic catalyst for synthesizing carbon nano-tubes and a manufacturing method of the carbon nano-tubes using the same are provided to suppress the generation of carbon impurities in the process of synthesizing the carbon nano-tubes by using nickel or cobalt as a catalytic metal. CONSTITUTION: A manufacturing method of a metallic catalyst for synthesizing carbon nano-tubes includes the following: a catalyst mixed solution containing a catalytic metal, molybdenum(Mo), and magnesium(Mg) at the molar ratio of 1:0.25:8.75 is prepared; the catalyst mixed solution is heated at a temperature between 400 and 500 deg C to prepare a catalytic material; and the catalytic material is pulverized to obtain catalytic powder. The catalytic metal is nickel(Ni) or cobalt(Co). A manufacturing method of the carbon nano-tubes includes the following: the metallic catalyst is prepared; the metallic catalyst is positioned on a substrate to be reacted with carbon source gas in a chamber in order to synthesize the carbon nano-tubes; and oxygen gas is further arranged in the chamber in the process of synthesizing the carbon nano-tubes.
