Strong structure sensitivity in the partial oxidation of styrene on silver single crystals
چکیده انگلیسی

In contrast to the formation of styrene oxide on Ag(1 1 1), phenylacetaldehyde and phenylketene dominate the partial oxidation of styrene on Ag(1 1 0), even though the reactions follow the same mechanism on both surfaces. The origin of this difference is that on Ag(1 1 0) the activation energy for transformation of the oxametallacycle to the combustion intermediate is much lower than on the (1 1 1) surface, so that ring-closure of the oxametallacycle to form styrene oxide is short circuited. Also the combustion intermediate appears more stable on Ag(1 1 0) than on Ag(1 1 1).
