Abstract

본 발명은 질소산화물(NOx) 정화용 촉매의 제조방법에 관한 것으로, 좀 더 상세하게는 제올라이트에 Rh를 이온교환시킨 후 Rh-제올라이트에 Cu를 이온교환시키는 것으로 이루어지므로써 촉매활성과 열적 내구성을 향상시킬 수 있는 NOx 정화용 촉매의 제조방법에 관한 것이다.The present invention relates to a method for preparing a catalyst for purifying nitrogen oxides (NOx), and more particularly, by ion exchange of Rh in zeolite and ion exchange of Cu in Rh-zeolite, thereby improving catalytic activity and thermal durability. The present invention relates to a method for producing a catalyst for purifying NOx.
