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 toleranceenOxygenalloyed Pt-NiCarbon electrocatalystAcid solutionCSIR Conference 2010Conference PresentationZheng, H., Rohwer, M.
