PURPOSE: A manganese-based catalyst for modifying the carbon dioxide of methane, a method for preparing the same, and a method for preparing synthetic gas using the same are provided to improve durability, stability, and activity of the catalyst by separately impregnating an active metal containing manganese in a support. CONSTITUTION: A manganese-based catalyst for modifying the carbon dioxide of methane is represented by chemical formula, X-Mn-Y/Z. In chemical formula, the X is platinum, palladium, rhodium, iridium, or ruthenium; the Y is zirconium or lanthanum; and the Z is a support based on silica or alumina. A method for preparing the catalyst includes the following: X components, manganese, and Y components are impregnated in the support; a mixture is obtained; the mixture is dried at a temperature between 50 and 110 degrees Celsius to obtain a dried product; and the dried product is fired at a temperature between 200 and 900 degrees Celsius. |
