Electrocatalysts for methanol oxidation was studied. They were prepared on the base of carbon nanotubes, covered by polyelectrolytes with differently charged functional groups, which was changed by platinum with subsequent reduction. Then ruthenium was spontaneous deposited on metal platinum. The prepared catalysts were more active compared to commertial ETEK Pt-Ru (50:50 at. %) catalysts.
