Hydrogenation of cinnamaldehyde over bimetallic Au-Cu/CeO2 catalyst under a mild condition

Effect of Au/Cu atomic ratios and thermal pretreatments on catalytic performance of AuxCuy/CeO2 for selective hydrogenation of cinnamaldehyde was studied. Reduction pretreatment lead to the higher catalytic performances due to the formation of Au-Cu alloy phase resulting in a homogeneous distribution of Au and Cu.216
