| Abstract: | Pt/sol and Pt/support catalysts with 6–15 Å Pt particles have been established to be low active in the hydrogenation of propargyl alcohol, butyn-l-ol-3 and dimethylethynylcarbinol. The specific catalytic activity significantly rises with increasing dPt above 15 Å and after the thermal treatment of highly dispersed catalysts in a hydrogen flow.
