Abstract

Metal nanoclusters can potentially exhibit high catalytic activity and selectivity due to not only a high number of exposed surface atoms but also active sites with different coordination numbers as compared to bulk catalyst surface. In this study ethylene hydrogenation was used as a model reaction in an effort to elaborate reactivity of small Ni nanoclusters and the ethylene hydrogenation reaction mechanism. Two mechanistic pathways; representing Eley-Rideal and Horiuti-Polanyi type of mechanism for ethylene hydrogenation reaction are studied. It has been concluded that Horiuti-Polanyi type is more favorable when compared to Eley-Rideal type.
