MARQUEZ-NAVARRO, Yara; GALICIA, Laura; LARA, Víctor Hugo  e  ANGEL, Gloria Del. Bi and Three-Metallic Electrocatalysts Preparation for Methanol Oxidation. J. Mex. Chem. Soc [online]. 2008, vol.52, n.1, pp.67-73. ISSN 1870-249X.

Bi and tri-metallic (Pt-Ru/C, Pt-Mo/C and Pt-Ru-Mo/C) catalysts were synthesized by using as precursors the metallic salts and applying the co-impregnation method. The tri-metallic catalysts underwent different thermal treatments and they were characterized by X-Ray. The catalytic activity for methanol oxidation reaction was determined by cyclic voltammetry (CV). The results show that the materials calcined before reduction presented the highest catalytic activity for methanol oxidation reaction.
