Abstract: Formic acid electrooxidation on Pd catalysts has been extensively investigated due to potential application in direct formic acid fuel cells. To improve the stability of catalysts and promote formic acid electrooxidation through the direct pathway, various Pd-based bimetallic catalysts has been received much attentions. In this work, the carbon-supported Pd-Ni (Pd-Ni/C) catalysts with different Pd/Ni atomic ratios are prepared by the impregnation-reduction method. These catalysts are characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS). The resulting physicochemical characterizations indicate that particle size, crystal structure and electron structure of Pd nanoparticles by adding Ni element. In addition, the effect of Pd/Ni atomic ratios on electrocatalytic performance of Pd-Ni/C catalysts for formic acid electrooxidation is also demonstrated by several electrochemical measures. It is observed that Pd-Ni/C catalyst with the suitable Pd/Ni atomic ratio exhibits excellent electrocatalytic performance and stability for the formic acid electrooxidation.
