Xenon-129 NMR Method for the Study of Heterogeneous Catalysts

초록

1980년대 발전된 크세논-129 핵자기 공명분광법은 제올라이트나 활성탄 또는 알루미나와 같은 다공성 물질에 크세논 기체를 흡착시킨 후에 기 기체중에 존재하는 천연동위원소 ¹²⁹Xe의 핵자기 공명신호의 화학적이동(chemical shift)이나 선폭(linewidth)으로부터 그 물질의 물리화학적 특성을 분석하는 방법이다. 현재까지 이 방법은 주로 제올라이트 촉매를 제조하거나 반응시키는 경우에 있어서 담지된 금속 물질의 위치와 화학변화및 담체 자체의 성질변화 등을 감지하는데 있어서 탁월한 것으로 알려져 있으며, 최근에는 이 방법이 활성탄과 실리카, 알루미나와 같은 비정형 물질에도 효과적으로 적용될 수 있다는 것이 발표되었다. 여기서는, 이 크세논-129 핵자기 공명 분광법의 원리와 실험방법 및 불균일계 촉매연구 분야에서 이 방법의 이용에 대한 최근의 연구결과들을 요약하여 소개한다.

Xenon-129 NMR technique has been developed since 1980 as a new method for the characterization of microporous materials such as zeolites, activated carbons and alumina by using chemical shift and linewidth variations in ¹²⁹Xe NMR of adsorbed xenon gas. This NMR technique has been known to be very effective to probe the locational and the chemical changes of the supported metallic species as well as the physicochemical change of the support material. Recently, this method has been successfully applied for the characterization of amorphous materials such as activated carbons, silica and alumina. Basic principles, experimental techniques and recent applications of the ¹²⁹Xe NMR method for the study of heterogeneous catalysts are introduced in this paper.
