摘要 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. 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 （grlR）. 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.
