PURPOSE: A direct decomposing catalyst manufacturing method for eliminating nitrous oxide is provided to shorten times required for manufacturing processes by omitting an ion-exchanging process. CONSTITUTION: Zeolite such as industrially acquired mordenite(MOR), ZSM-5, natural zeolite, FAU is prepared as the carrier of a catalyst(S100). A catalytic active material is carried in zeolite by mixing a reagent in the form of oxide or chloride containing the catalytic active material with the zeolite(S200). The resultant product is dried(S300). The resultant product is plasticized at a temperature of 500 to 800 degrees Celsius to obtain a catalyst(S400). The catalyst is steam-treated at a temperature of 500 to 800 degrees Celsius according to the crystalline state of the catalyst. |
