Selective catalytic hydrogenation of unsaturated carbonyl compounds was studied on bimetallic Ru-Sn/TiO2 catalysts. The catalysts were prepared by a sol-gel method and co-impregnation in order to evaluate selected parameters (amount of the modifying tin, TiO2 support - commercial, standard sol-gel, modified sol-gel) on their catalytic activity and selectivity. Significant tin effect was proved especially with regard to the positive influence on selectivity. Sol-gel modified TiO2 was found to be the optimum support. Furthermore, the effect of substrate was studied. The suitability of the catalytic system for hydrogenation of unsaturated aldehydes was proved but it is not suitable for selective hydrogenation of unsaturated ketones.
