Abstract

The aim of this study is to test the feasibility of Pt/Al-MCM-41 for the dioxin decomposition reaction. For model reaction, 1,2-dichlorobenzene was decomposed instead of dioxin. $Pt/{\gamma}-Al_2O_3$ was compared with Pt/Al-MCM-41. Al-MCM-41 catlaysts were prepared by post grafting method and the Pt/Al-MCM-41 catalysts with Si/Al = 15, 30 showed higher catalytic activity than $Pt/{\gamma}-Al_2O_3$. Their higher catalytic activities were related with acid amounts. Especially Al-MCM-41 with ion exchanged with $H^+$ enhanced catalytic activity.

본 연구의 목적은 다이옥신 분해 촉매 반응에 Pt/Al-MCM-41 메조포러스 촉매를 이용할 수 있는 가능성을 알아보고자 하는 것이다. 다이옥신 분해 반응에 대한 모델 반응으로 1,2-dichlorobenzene 분해 반응을 실시하였다. 비교 촉매로는 $Pt/{\gamma}-Al_2O_3$ 촉매를 사용하였다. Post grafting 방법으로 Al-MCM-41 촉매를 제조하여 실험한 결과, Si/Al = 15, 30인 Pt/Al-MCM-41 촉매가 $Pt/{\gamma}-Al_2O_3$ 촉매 보다 우수한 활성을 나타내었다. 이러한 반응 활성은 산점의 양과 밀접한 관계를 나타내었다. 특히 Al-MCM-41을 H-form으로 이온교환하여 반응 실험에 적용한 결과, 활성이 더욱 더 증대되었다.
