| Abstract: | Alloyed electrocatalysts such as PtNi/C[1-2], PtCo/C[3], PtCr/C[4], PtFe/C [5-6], and non-alloyed Pt-TiO2/C were reportedly investigated for methanol tolerance during Oxygen reduction reaction (ORR). The high methanol tolerance of these electrocatalysts during the ORR was attributed to a composition effect, disordered stucture and low activity for methanol oxidation reaction. Most Pt alloy electrocatalysts were prepared via a complex procedure or by high temeperature thermal reduction. In this work, Pt3Ni/C alloy electrocatalysts were synthesised by a simple route at low temperature, resulting in a highly-alloyed product with high ORR activity and excellent methanol tolerance |
