Carbon nanotubes supported core–shell catalysts Pt-Ru/Ni, Pt-Ru/Pb and Pt-Ru/Ni for methanol oxidation reaction in fuel cell

The core-shell type catalysts were obtained by spontaneous surface substitution of electrodeposited Pb, Ni and Cu by platinum metals Pt-Ru. The surface layer of obtained catalysts was tested by EDAX; the amount of platinum was determined by ICP-AES. The catalytic activity of obtained catalysts was examined in methanol oxidation reaction. The stationary state currents were referred to EAS, determined from hydrogen adsorption. For all investigated systems the catalytic effect was registered thus confirming the activity of core–shell catalyst.
