Abstract

The hydrogenation of crotonaldehyde was studied over five catalysts with platinum as the major catalytically active component. The catalytic activity for hydrogenation of the C=O bond decreased in the order PtGa/SiO₂>Pt/Ti0₂>PtSn/TiO₂>PtNi/Si0₂. Pt/SiO_a was one order of magnitude less active than the other catalysts investigated and catalyzed only the hydrogenation of the C=C bond. Two different types of sites were concluded to be active for C=O bond hydrogenation, i.e., (i) the metal-oxide-interface (i.e. Pt-TiO_x and Pt-GaO_x) and (ii) bimetallic moieties as in Pt-Sn and Pt-Ni with a small positive charge on the less noble constituent. Hydrogenation of the C=C bond was concluded to occur primarily on the pure metal surfaces.
