Funcational multi-wall carbon nanotubes(MWNT)supported platinum and ruthenium electrocatalyst Pt-Ru/ MWNT with high dispersion were prepared by a modified electro-deposition method.The structures,compositions and valences of the catalysts were measured by Transmission Electron Microscope(TEM)and Infrared spectrum(FTIR).The methanol electro-oxidation activity and stabilization was measured by CV,and a better electro-oxidation activity was gain.The results show that oxygen containing groups were produced on the surface of MWNT to facilitate the Pt and Ru nanoparticle absorption,the diameter of particle is 5~15nm.
