PURPOSE: A copper-chrome reaction catalyst is provided to increase activation point by introducing a palladium which is a precious metal into a copper-chrome catalyst, thereby having high activity even under a low hydrogen partial pressure, thereby being applied to a continuous process as a pellet shape. CONSTITUTION: A copper-chrome reaction catalyst of 1,2-propanediol comprises a metal element, and a copper-chrome catalyst. The metal element is a co-catalyst of a copper-chrome catalyst. A manufacturing method of the 1,2-propanediol comprises a step of preparing a metal precursor solution by dissolving a metal precursor compound into a solvent; a step of forming a precipitate by controlling pH of the metal precursor solution; a step of measuring the precipitate; a step of filtering and drying the precipitate; a step of incinerating the dried precipitate; and a step of adding an organic binder into the catalyst powder, pasting, and extrusion-molding the same.
