Bi and Three-Metallic Electrocatalysts Preparation for Methanol Oxidation

Bi and tri-metallic (Pt-Ru/C, Pt-Mo/C and Pt-Ru-Mo/C)catalysts were synthesized by using as precursors the metallic saltsand applying the co-impregnation method. The tri-metallic catalystsunderwent different thermal treatments and they were characterizedby X-Ray. The catalytic activity for methanol...

Sumario:Bi and tri-metallic (Pt-Ru/C, Pt-Mo/C and Pt-Ru-Mo/C)catalysts were synthesized by using as precursors the metallic saltsand applying the co-impregnation method. The tri-metallic catalystsunderwent different thermal treatments and they were characterizedby X-Ray. The catalytic activity for methanol oxidation reaction wasdetermined by cyclic voltammetry (CV).The results show that the materials calcined before reduction presentedthe highest catalytic activity for methanol oxidation reaction.
