    • 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.

    • PURPOSE: A manufacturing method for a metal- or metal oxide-supported catalyst using a melt-infiltration process with a metal hydrate salt and a metal- or metal oxide-supported catalyst thereof are provided to easily and quickly mass produce the metal- or metal oxide-supported catalyst by using a nitrate hydrate metal salt or a chloride hydrate metal salt with a low melting point. CONSTITUTION: A manufacturing method for a metal- or metal oxide-supported catalyst using a melt-infiltration process with a metal hydrate salt comprises the following steps: The metal hydrate salt is mixed with a metal substrate with a porous structure. After the mixing process, the mixture is melted at the melting point of the metal hydrate salt such that the metal hydrate salt infiltrates into the substrate. The metal hydrate salt infiltrated in the supporter is plasticized at a high temperature and chagrined to nanoparticles. The metal hydrate salt has a melting point within 35 - 120 deg. C.
