In this work, Pt-Ru catalysts deposited on binary carbon supports using multi-walled carbon nanotubes (MWNTs) and ordered mesoporous carbons (OMCs) were developed for direct methanol fuel cells (DMFCs). The electrochemical characteristics for methanol oxidation were evaluated by cyclic voltammetry with 1 M CH3OH in a 0.5 M H2SO4 solution as electrolyte. This was attributed to the introduction of MWNTs as a secondary support, which provided a highly accessible surface area and morphological changes of the carbon supports. Consequently, the Pt-Ru nanoparticles deposited on the binary support exhibited better performance than the single support. |
