In a joint experimental and theoretical approach, subnanometer to up to 23 nm sized silver clusters that utilize molecular oxygen were identified for the partial oxidation of propene. The particles exhibited strongly size-dependent catalytic activity and selectivity towards the formation of propylene oxide or acrolein under mild reaction conditions.
