Abstract

Perovskite-type oxides were successfully prepared using malic acid method, characterized by TG/DTA, XRD, XPS, TEM and $H_2$-TPR and their catalytic activities for the combustion of benzene were determined. Almost of catalyst showed perovskite crystalline phase and 15-70 nm particle size. The $LaMnO_3$ catalysts showed the highest activity and the conversion reaches almost 100% at $350^{\circ}C$. The catalysts were modified to enhance the activity through substitution of metal into the A or B site of the perovskite oxides. In the $LaMnO_3$-type catalyst, the partial substitution of Sr into site the A-site enhanced the catalytic activity in the benzene combustion. In addition, the partial substitution of Co or Cu into site the B-site also enhanced the catalytic activity and the catalytic activity was in the order of Co > Cu > Fe in the $LaMn_{1-x}B_xO_3$ (B = Co, Fe, Cu) type catalyst.

페롭스카이트형 산화물을 능금산법으로 합성하여 TG/DTA, XRD, XPS, TEM 및 $H_2$-TPR 등에 의해 특성분석을 하였고, 벤젠의 연소반응에서의 활성을 조사하였다. 대부분의 촉매들은 페롭스카이트 결정구조를 잘 가지고 있었으며 15에서 70 nm의 크기를 나타내었다. $LaMnO_3$ 촉매가 가장 높은 활성을 보여주었고 $350^{\circ}C$에서 거의 100%의 전환율을 나타내었다. 반응활성을 증가시키기 위해 페롭스카이트 산화물의 A-와 B-위치에 다른 금속이온의 치환을 행하였다. $LaMnO_3$ 촉매의 A-위치에 Sr을 일부분 치환시키면 벤젠의 전환율이 증가하였다. 또한, B-위치에 Co 및 Cu 이온의 치환 역시 촉매 활성을 증가시켰고, $LaMn_{1-x}B_xO_3$ (B = Co, Fe, Cu)형 페롭스카이트에서 촉매활성은 Co > Cu > Fe의 순서로 감소하였다.
