Abstract
백금담지촉매의 수소 Spillover 현상을 선택적인 화학흡착과 Cyclohexene의 기상수소화 반응으로 조사하였다. 수소의 가역흡착량과 수소 Spillover되는 양의 관계를 반응기구와 수소 Spillover의 개요도로 설명하였다. 담체나 희석제에 따라 반응활성도는 영향을 받지만 수소 Spillover가 일어나더라도 활성화에너지나 반응기구는 변화가 없다.
Hydrogen spillover phenomena on supported Pt catalysts were studied by means of selective chemisorption and vapor phase hydrogenation of cyclohexene. To illustrate the relation between the reversible hydrogen uptake and the amount hydrogen spillovered, reaction mechanism and diagram of hydrogen spillover were used. Reaction activity was influenced by the supports and diluents, but activation energy and reaction mechanism did not change even if hydrogen spillover occurred.
