N2 - The use of supported nanoparticles of metal alloys as the active component makes it possible to modify the activity, selectivity, and stability of conventional monometallic supported heterogeneous catalysts. An approach to directed synthesis of bimetallic powders and supported catalysts based on the decomposition of double complex salts in the pores of the support is described. The efficiency of the proposed strategy was shown earlier by the example of catalysts for hydrogen production and purification processes: Pt0.5Co0.5/SiO2 and Au0.4Cu0.6/CeO2 catalysts for preferential oxidation of CO. Nanopowders of Pt0.5M0.5 (M = Fe, Co, Cu) and Pt0.33Ag0.67 and supported Pt0.5Cu0.5/Ce0.75Zr0.25O2 and Pt-CuOx/Ce0.75Zr0.25O2 catalysts are obtained in this work. It is shown that the nanopowders possess catalytic activity in the reaction of preferential CO oxidation in excess H-2, while the Pt-Cu supported catalysts, in the low-temperature water gas shift reaction.
