Abstract: Cerium–zirconium mixed oxides with different Ce/Zr ratio were prepared and used as supports for Pt-containing catalysts. The study of the catalysts in the cinnamaldehyde hydrogenation reaction has shown that cinnamaldehyde conversion and cinnamyl alcohol selectivity strongly depend on the CeO₂ content in the support. The highest cinnamyl alcohol yield of 81% was obtained in 105 min at room temperature and atmospheric pressure over the 1%Pt/CeO₂–ZrO₂ catalyst with Ce : Zr atomic ratio equal to 4 : 1.

Keywords: cinnamaldehyde, cinnamyl alcohol, cerium oxide, zirconium oxide, selective hydrogenation, unsaturated alcohol synthesis, platinum, α,b-unsaturated aldehydes.
