摘要：

Hydrogenation of cinnamaldehyde has been investigated over a series of Ru-Sn/C catalysts having various Sn/Ru ratios. Addition of tin to Ru/C decreases the CO chemisorption capability of the catalyst. The overall turnover frequency of cinnamaldehyde disappearance and the selectivity to cinnamyl alcohol increase with the Sn/Ru ratio. It is suggested that hydrogenation of the -C = O group occurs on sites associated with tin ions. On these sites the carbonyl group is polarized, facilitating hydrogen transfer from an adjacent Ru-H site.
