ABSTRACT:

Reactions of H2 and CO over a Ni(100) model catalyst have been studied. Measurements of the surface carbon concentrations and the product yields show that, for a fixed carbon level, the amounts of higher molecular weight hydrocarbons are strongly dependent on the reactant carbon monoxide pressure, and suggest a formation mechanism that involves a CO insertion step.
