The pressure's off : The coupling of propylene ( 1 ) to generate benzene ( 2 ) at 70 °C and atmospheric pressure was observed together with propylene hydrogenation and oxygenation on titania‐supported Pd nanoclusters (in green). The catalysts consist predominately of metallic Pd 0 . The selectivity of benzene formation is dependent on cluster size (Ø=3–12 nm) and the presence of both hydrogen and oxygen.
