Electronic effects: The unusual reactivity of the Ag monolayer compared to the bulk Ag surface on Si(111) (see figure) is due to the confinement of the 5sp electrons. This change in reactivity has significant effects on the surface activity and selectivity, which could result in novel catalytic properties.
