More Greasy, More Selective: Amine-capped Pt3Co nanocatalysts were synthesized and used for the hydrogenation of cinnamaldehyde (CAL). Capping the catalysts with amines that contain long carbon chains results in an ordered surface “array” (see scheme), in which high selectivity towards C[DOUBLE BOND]O hydrogenation can be achieved because the C[DOUBLE BOND]C bond in CAL does not interact with the surface. The longer the carbon chains in the amine, the higher the selectivity.
