Abstract

(Hydr-) oxidic PdOxHy colloids were prepared by H2PdCl4 hydrolysis in presence of poly(vinylpyrrolidone) under pH control. After immobilization, the resulting catalysts show a high chemo- and stereo selectivity in the hydrogenation of C–C triple bonds. Systematic investigations of the preparation parameters indicate that the hydrolysis pH, the PVP amount and chainlength as well as the colloid aging time are of major importance for catalytic performance.
