Provided is a porous carbon material having carbon nano-rods on the surface thereof. The porous carbon material has an increased specific surface area and an increased electrochemically active area, and thus may be expected to provide improved performance, when used as an electrode for electrochemical reactions. In addition, the carbon nano-rods of the porous carbon material are formed through an etching process using a catalyst for etching formed on the carbon material, and thus the carbon material may have various functions.
