Abstract: A catalyst for removing nitrous oxide, a method for producing the same, and a method for removing the nitrous oxide using the same are provided to improve the efficiency in removal of the nitrous oxide, by preparing the catalyst using mordenite zeolite as a carrier. A catalyst for removing nitrous oxide is formed by supporting at least one of transition metal and noble metal on a mordenite zeolite carrier. The catalyst is prepared by washing the mordenite zeolite(S300), drying the washed mordenite zeolite(S320), immersing at least one of the transition metal and noble metal in the mordenite(S350), drying the mordenite zeolite(S360), and hardening the dried mordenite zeolite(S370). Further, the transition metal is Fe, and the noble metal is Pd.
