Abstract

The catalytic thermal oxidizer process has recently attracted considerable attention for the oxidation and decomposition of volatile organic compounds at low temperatures (< 450 ℃) with high efficiency (> 95%). Although many noble metal catalytic materials are well established, they are expensive and hazardous. Herein, highly active and low-cost Cu-Mn bimetallic catalysts were prepared using a simple and facile synthesis method involving the co-precipitation of Cu and Mn precursors. The synthesis of the catalyst was optimized by controlling the composition ratio of Cu and Mn. The optimized catalyst exhibited a large surface area of 230.8 m2/g with a mesoporous structure. To demonstrate the catalytic performance, the Cu-Mn catalyst was tested for the oxidation reaction of ethyl acetate, showing a high conversion efficiency of 100% at a low temperature of 250 ℃.

최근 촉매 소각 공정은 휘발성 유기 화합물을 저온(< 450 ℃)에서 고효율(> 95%)로 산화 및 분해하기 위해 상당한 주목을 받고 있다. 많은 귀금속 촉매 물질이 잘 연구되어 사용되고 있으나 단가가 비싸고 위험하다. 본연구에서는 Cu와 Mn 전구체의 공침법을 활용하여 간단하고 손쉬운 합성 방법을 개발함으로써 고활성 및 저비용의 Cu-Mn 바이메탈 촉매를 제조하였다. 촉매 합성은 Cu와 Mn의 조성비를 조절하여 최적화하였다. 최적화된 촉매는 메조포러스 구조로 230.8 m2/g의 넓은 표면적을 나타냈다. 촉매 성능을 입증하기 위해 에틸 아세테이트의 산화 반응에 대해 Cu-Mn 촉매를 테스트했으며, 250 ℃의 저온에서 100%의 높은 전환 효율을 나타내었다.
