Abstract: PURPOSE: A transition metal oxide / multi-walled carbon nanotube nanocomposite and a method for manufacture the same are provided to enable mass production through a simple synthesis procedure by manufacturing 0 dimension -1 dimension nanocomposite using an urea composition method and a surfactant. CONSTITUTION: A method for manufacturing a transition metal oxide / multi-walled carbon nanotube nanocomposite comprises the following steps: a first step of dissolving a surfactant by putting the surfactant into deionized water; a second step of uniformly dispersing carbon nanotube and the surfactant by putting multi-walled carbon nanotube into a solution of the first step; a third step of adding chloridation metal and urea in the solution of the third step; a fourth step of heating the solution of the third step to 95 ~ 105 °C while stirring the solution; a fifth step of obtaining a precipitate by refluxing the solution of the fourth step; and a sixth step of manufacturing the nanocomposite by heat-treating the precipitate under air atmosphere or vacuum.
