    Abstract: Provided according to an embodiment are a carbon electrode material and a method for preparing same. The method comprises the steps: mixing a carbon precursor powder, a molding powder, and a metal precursor powder to form a mixed powder; and thermally treating the mixed powder to form a nitrogen-doped carbon composite, wherein: the molding powder includes a metal-organic framework (MOF); the carbon precursor powder is contained in an amount of 10 wt % to 20 wt % on the basis of the total mixed powder; the molding powder is contained in an amount of 50 wt % to 80 wt % on the basis of the total mixed powder; the metal precursor powder is contained in an amount of 0.1 wt % to 5 wt % on the basis of the total mixed powder; and the carbon composite has a monoatomic or nanometer-unit sized metal located therein.
