Abstract
Selective hydrogenation of crotonaldehyde to the corresponding unsaturated alcohol, crotyl alcohol, has been investigated over Sn-modified SiO 2-coated Pt catalyst. Tin-modified SiO 2-coated Pt (Sn/SP) catalyst was proposed as a new concept catalyst, in which roles of Sn (to activate the CO group of crotonaldehyde) and Pt (to activate H 2) were totally separated. TEM and EXAFS experiments for Sn/SP calcined at 823 K and reduced by H 2 at 573 K confirmed that Sn species were separate by impregnated from the core Pt nanoparticles. The selectivity toward crotyl alcohol over the Sn/SP catalysts calcined at 823 K and reduced by H 2 at 573 K attained 100% with 4.1% of yield. These results suggest that the reaction between the activated crotonaldehyde on SnO 2 sites and H 2 dissociatively adsorbed on Pt proceeds over the Sn/SP catalysts.
