Abstract: PURPOSE: A manufacturing method of a catalyst and a manufacturing method of propanediol using the same are provided to produce propanediol from glycerol with high yield at a low temperature and pressure condition. CONSTITUTION: A manufacturing method of a catalyst includes the following steps: preparing a metal precursor solution by dissolving a metal precursor in a solvent; preparing a support containing metals dipped in the metal oxide by agitating and mixing the metal oxide in the metal precursor solution; removing the solvent; pulverizing and drying the support containing the metal; and calcinating the support containing the metal. The manufacturing method of the catalyst further includes a step for reducing the catalyst to increase catalytic activity. The metal of the metal precursor is ruthenium, platinum, rhodium or palladium.
