Abstract: PURPOSE: A method for manufacturing a metallic catalyst including a carbon carrier in which a fluorine functional group is introduced is provided to control a size of the catalyst when a new fluorine functional group is introduced to the carbon carrier and to enhance an activity of catalyst by increasing a dipping efficiency of the mixing metal. CONSTITUTION: A method for manufacturing a metallic catalyst comprises: a pre-treatment step(a) for eliminating impurities on the surface; a step of manufacturing a carbon carrier in which a fluorine functional group is introduced by directly performing a fluorination treatment to the carbon carrier; and a step(b) of manufacturing the metallic catalyst by dipping the metal in the carbon carrier. The fluorination treatment to the carbon carrier in the step(a) is performed under 0.01 - 1 MPa for 1 - 30 minutes. A temperature range of the fluorine treatment to the carbon carrier is from room temperature to 800°C in the step(a).
