초록

조합 및 고속탐색 실험 기법을 촉매 성분의 선정에 활용하였다. 소형 연료전지 작동을 위한 수소 생산에 가장 적합한 것으로 알려진 메탄을 산화 분해용 촉매의 특성을 적외선 화상 및 병렬형 반응 시스템으로 조사하였다. 반응의 모델을 먼저 제시하고 이를 근거로 Cu-Zn-Pd계 촉매를 선정하였다. 먼저 적외선 화상을 이용한 스크리닝을 위해서는 발열 효과라는 촉매 활성의 간접적인 현상을 보여줄 수 있는 적외선 민감 카메라를 이용하여 한 번에 50개의 시료 측정이 가능한 촉매 시료 배열을 설계하였다. 적외선 화상 결과로 높은 활성을 보이는 촉매 시료를 선정한 다음, 병렬형 반응 시스템과 단일 흐름 고정층 반응 시스템으로 선정된 촉매의 활성 특성을 조사 확인하였다. 본 연구에서 제시한 것과 같은 접근 방법으로 지속적으로 얻어진 결과를 반영하여 최적의 활성을 보이는 촉매 성분을 단기간에 찾아내고자 한다.
