다양한 금속담지촉매에서 수소 spillover 현상을 수소흡착과 벤젠의 기상수소화반응으로 조사하였다. 금속으로부터 담체나 희석제 위로 이동하는 수소에 기인하여 촉매와 접촉하고 있는 희석제의 양을 증가시킴에 따라 수소흡착량은 증가했다. 그러나 반응활성도는 회석제로 희석함에 따라 증가하다가 더 많이 희석하면 감소하였다. 얻어진 결과들을 double spillover 효과, 이동거리 및 담체나 희석제 위에서 이동하는 수소끼리의 재결합으로 설명하였다. 희석률이나 반응온도에 따라 반응활성도는 영향을 받지만 수소 sillover가 일어나더라도 활성화에너지나 반응기구는 변화가 없었다.

Hydrogen spillover phenomena on various supported metal catalysts were studied by means of hydrogen chemisorption and vapor phase hydrogenation of benzene. Enhancement of the adsorption of hydrogen by increasing the amount of diluents in contact with the catalysts was the result of migration of the spillover hydrogen from the metal to the support and diluent. However, the reaction activity increased with the degree of dilution of the catalysts with the diluents and then decreased in more diluted systems. The results obtained could be interpreted by the double spillover effect, the migrating distance and the recombination of hydrogen on the supports and diluents by collision. The reaction activity was influenced by the dilution ratio and the reaction temperatures, but the activation energy and the reaction mechanism did not change even if hydrogen spillover occurred.
