Perovskite 型 酸化物 觸媒를 利用한 一酸化炭素와 酸化窒素의 酸化還元反應을, 排氣가스 處理用 貴金屬 觸媒 代替 硏究의 一環으로 行하였다. ABO₃ 및 A_(1-x)A`_xBO₃ 形態의 Perovskite 型 酸化物을 實驗室的으로 製造한 後, X-線 回折分析을 通하여 이들의 構造를 確認하였고, 循環式 回分反應器를 利用하여 이들의 觸媒活性, 酸化還元, 反應機構, 反應速度 等을 調査하였다.

Perovskite-type catalyrsts 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-x)A`_xBO₃ were prepared in the laboratory and their structures were confirmed by X-ray diffraction analysis. The activities cf catalysts, redox reaction mechanism, and reaction kinetics were studied in a batch recycle-type reactor.
