Selective hydrogenation of citronellal to citronellol over polymer-stabilized noble metal colloids

摘要

Citronellal was hydrogenated to citronellol by polymer-stabilized Pt and Ru colloids. The metal cations increased both the activity and the selectivity of the colloics. The modification was assumed to be due to the adsorbed metal cations activating the C=O doble bonds, thus accelerating the reaction rate and increasing the selectivity to unsaturated alcohols.
