Περίληψη:	Platinum nanoparticles as spherical aggregates were prepared by the reduction of a Pt(II) salt with hydrazine using 3,3́-thiodipropionic acid as a protective agent, and characterized by IR, XRF, XRD, and SEM where agglomerates have been visualized. The average crystallite size was 6 nm. For the first time such nanoparticles were evaluated as catalysts in the hydrogenation of unsaturated aldehydes. Hydrogenation of trans-cinnamaldehyde yielded cinnamyl alcohol with a selectivity of up to 83% at complete substrate conversion. At 30 C, the catalyst could be recycled and reused for three runs with only slight losses in activity and selectivity.
