Abstract

Perovskite형 산화물 촉매를 이용한 일산화탄소와 산화질소의 산화환원반응을, 배기가스 처리용 귀금속 촉매 대체연구의 일환으로 행하였다. ABO₃ 및 A_1-xA'_xBO₃형태의 Perovskite형 산화물을 실험실적으로 제조한 후, X-선 화절분석등을 통하여 이들의 구조를 확인하였고, 순환식 회분반응기를 이용하여 이들의 촉매활성, 산화환원 반응기구, 반응속도 등을 조사하였다.

Perovskite-type catalysts were used for the reduction of nitric oxide with carbon monoxide as an alternative to precious metals, current commercial catalysts, for the neutralization of automobile emission gases. The perovskite-type oxides in the form of ABO₃ and A_1-_xA'_xBO₃ were prepared in the laboratory and their structures were confirmed by X-ray diffraction analysis. The activities of catalysts, redox reaction mechanism, and reaction kinetics were studied in a batch recycle-type reactor.
