Abstract: Disclosed herein are a catalyst for low-temperature carbon monoxide purification, a method for manufacturing the same, and a method for purifying carbon monoxide using the same. The catalyst comprises a metal oxide carrier; a transition metal oxide primarily supported on the carrier, and ruthenium secondarily supported on a carrier carrying the transition metal oxide. The catalyst provides an effect capable of purifying carbon monoxide contained in a hydrogen gas at a low temperature.
