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 CO group occurs on sites associated with tin ions. On these sites the carbonyl group is polarized, facilitating hydrogen transfer from an adjacent RuH site.

Abstract

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 CO group occurs on sites associated with tin ions. On these sites the carbonyl group is polarized, facilitating hydrogen transfer from an adjacent RuH site.
