A new method for the synthesis of nRu center dot mPt center dot(Hx-3n-2mMoO3) composite based on the redox reaction between the reduced forms of molybdenum bronzes and the solution containing platinum and ruthenium species is proposed. The uniform distribution of Pt and Ru over the electrode surface was observed in the case of their codeposition from the solution containing both platinum and ruthenium compounds. The obtained composite contained platinum mainly in the metallic state, while ruthenium was found in both metallic and oxidized states. The manufactured electrodes were characterized by high catalytic activity in the reactions of carbon monoxide and methanol oxidation. The rate of the methanol oxidation reaction (MOR) on nRu center dot mPt center dot(H(x-3n-2m)MoO3) was 4-5 times higher in comparison with that on nPt center dot(Hx-2nMoO3) and similar to 30 times higher as compared with that on Pt-ed/GC. On the basis of the obtained data, one can state the additive effect of ruthenium and molybdenum species on methanol electrooxidation. (C) 2018 Published by Elsevier Ltd.
