An Effective Pt-CuSiO2 Catalyst for the Selective Hydrogenation of Cinnamaldehyde

الملخص EN

The bimetal catalyst Pt-Cu/SiO2 was prepared by the impregnation method.

Its catalytic performance was investigated by the selective hydrogenation of cinnamaldehyde.

Pt-Cu/SiO2 exhibited much higher selectivity (64.1%) to cinnamyl alcohol than Pt/SiO2 (3.7%), while they showed similar conversion of cinnamaldehyde.

This enhancement was attributed to the increase in the amount of the Pt0 species on the Pt-Cu/SiO2 surface, which is derived from the interaction between Pt and Cu revealed by XRD and XPS.
