Abstract: PURPOSE: A highly loadable and dispersive metal-oxide/carbon nano catalyst carrier and a production method thereof are provided to easily obtain catalysts in which metal-oxide particles are well dispersed along with carbon residues by removing excessive carbon substances which exists in a porous carbon molding frame. CONSTITUTION: A production method of highly loadable and dispersive metal-oxide/carbon nano catalyst carrier comprises the following steps; a mixing step which mixes metal-salt hydrate with a carbon molding frame in a porous structure; an impregnation step which impregnates the metal-salt hydrate in the carbon molding frame after melting and impregnating around the melting point of the metal-salt hydrate; a drying step which dehydrates the obtained mixed powder; and a removal step which forms metal oxide particles by sintering the carbon molding frame, in which the metal-salt hydrate is loaded, and removes carbons from the carbon molding frame leaving the partial amount of carbon. A sintering temperature above is ranged from 200 to 700 deg. C, and a sintering period is ranged from 30 to 48 hours.
