The preparation of supported bimetallic catalysts was examined by selective deposition of metal complex precursors on the surface of the first metal particles. A Pt-Ru/SiO2 catalyst was prepared using Pt/SiO2 and ruthenocene as starting materials. Analysis of the surface structure by means of O-2-CO titration suggested that Ru metals covered the surface Pt atoms without forming separate Ru particles. This technique was applied for the preparation of an egg-shell type of the Pd-Fe bimetallic catalyst supported on alumina, using ferrocene as a precursor of iron. Pt-Sn bimetallic catalysts were prepared by selective deposition of tetramethyl tin on Pt particles. Liquid-phase deposition was tried in the case of Pd-Ag and Pd-Au catalysts supported on alumina. Selective deposition of Ag and Au on Pd surface was observed, and the selectivity to 1-butene was increased in the partial hydrogenation of 1,3-butadiene.
