Abstract: SnOx-modified Pt2Ru3/C catalysts were post-treated in different atmospheres at various temperatures to improve the catalytic activity for H2/CO electro-oxidation. The structures of the Pt2Ru3/C and SnOx/Pt2Ru3/C catalysts were characterized by X-ray diffraction. Electrochemical activities were evaluated by CO stripping voltammetry and single cell test. The SnOx/Pt2Ru3/C catalysts had a lower onset potential for CO electro-oxidation and greater cell voltage than the Pt2Ru3/C catalyst under high CO concentrations. The SnOx/Pt2Ru3/C catalyst treated in 5 % H2/Ar at 150℃ exhibited the greatest CO tolerance due to that the post-treatment caused the conversion of SnO2 to SnOx (1≤ x ≤2) without destroying PtRu alloy structure.
