The materials were prepared by the borohydride process. X-ray diffraction (XRD) patterns of PdAu materials showed peak characteristic of Pd and Au face-centered-cubic (fcc) structures while transmission electron micrographs (TEM) showed the nanoparticles with particle size between 4 and 10 nm for all electrocatalysts. Experiments considering single cell suggested the PdAu/C (90:10) and PdAu/C (80:20) as promisors for formate oxidation. The best result obtained was attributed to the presence of Au in small quantities that contributes to the formate adsorption.442-446openAccesselectrocatalystsanodespalladiumgoldcarbonboron hydridesfuel cellsliquid fuelsx-ray diffractionArtigo de periódico610.1007/s12678-015-0262-1https://orcid.org/0000-0002-9287-6071https://orcid.org/0000-0002-7011-826162.89
