Pd and bimetallic PdRu nanoparticles supported on Vulcan XC-72 carbon prepared by the microwave-assisted polyol process are examined as electrocatalysts for the electrooxidation of formic acid. The catalysts are characterized by transmission electron microscopy and Xray diffraction. The Pd and PdRu nanoparticles with sizes of <10 nm display the characteristic diffraction peaks of a Pd face-centered cubic (fcc) crystal structure. It is found that the addition of Ru to Pd/C can decrease the lattice parameter of Pd (fcc) crystal. The electrocatalytic activities of the catalysts are evaluated in sulfuric acid solution containing 1 M formic acid using linear sweeping voltammetry and chronoamperometry. The results show that Pd5Ru1/C displays the best electrocatalytic performance among all catalysts for formic acid electrooxidation.
