Beschreibung
Zusammenfassung:	One embodiment of the present disclosure provides a method of preparing a catalyst for manufacturing carbon nanotubes, which includes: (a) dissolving a metal precursor in a solvent to prepare a precursor solution; (b) thermally decomposing the precursor solution by spraying the precursor solution into a reactor; and (c) obtaining a catalyst, wherein the catalyst includes a metal component represented by the following Chemical Formula 1: [Chemical Formula 1] Cox:[M1, Zr]y:M2zwherein Co represents cobalt or oxides or derivatives thereof, M1 represents at least one metal, or oxides or derivatives thereof, selected from Al, Ca, Si, Ti, and Mg, Zr represents zirconium, or oxides or derivatives thereof, M2 represents at least one metal, or oxides or derivatives thereof, selected from W, V, Mn, and Mo, x/y satisfies 0.2 ≤ x/y ≤ 2.6, and x/z satisfies 6 ≤ x/z ≤ 13.
