Abstract

본 발명은 니켈 및 코발트 및 임의로 구리원소에서 선택된 적어도 1종의 원소를 함유하는 디젤 엔진의 배기 가스 정화용 촉매를 제공한다. 또한, 본 발명은 상기 원소 및 내화성 무기 산화물을 함유하는 촉매 성분이 담지되어 있는 내화성 3차 구조물로 이루어진 디젤 엔진의 배기 가스 정화용 촉매를 제공한다. 이 촉매는 디젤 엔진의 배기 가스중에 함유된 유해 성분, 예컨대 탄소질 미립자, 불연소 탄화수소, 일산화탄소등을 저온에서 부터 연소시킴으로써 제거할 수 있고, 또한 이산화황으로 부터 황산염의 형성을 억제시킬 수 있다.
