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.eninfo:eu-repo/semantics/closedAccessNi nanoclusterDFTEthylene hydrogenation mechanismActivation barrierMagic numberConference Object10.1007/s11244-013-0043-0569-10789793WOS:000320500200034Q2Q2
